I think if he meant Greg Ginn he would've just said Greg Ginn. It's got the same number of syllables and would've easily fit into the song. If a guys singing a song about iconic asshole punk rockers and he says G.G. he means G.G. Allin. There's only one G.G.

1. "Tom took his life in his mother's car": Tom Clements, from 'Give You Nothing', died in a car accident in 1986.

2. "Milo went to college but you knew about that": Milo Aukerman from the Descendents, also "Milo goes to college" is the title of one of the Descendents albums. He has a Ph.D. in biochemistry from the University of Wisconsin, Madison

3. "Rodney played our record": Rodney "on the rock" show from local Southern California station KROQ who played Bad Religion for the first time on the radio.

4. "GG started riots": Greg Ginn of Black Flag because there were riots at a lot of Black Flag shows. It could be GG Allen as well since he was one crazy guy so riots fits perfectly, but he wasn't from L.A.

5. "Laurie was always quiet, she was battling depression": This could possibly be Laurie Anderson, the only one alternative/punk music in the business I can think of with the name Laurie.

5. "Jack wore a skirt but he knew how to scrap": Jack Grisham, singer for TSOL, he was known to wear a skirt on stage.

6. "Billy went to county on a class one possession": Brett himself (as in No Control/Into the Unknown's Billy Gnosis) This was reference to when he was caught with ten balloons of heroin and was ordered by the court to go to rehab.

7. "Wendy went to school while her daddy shot smack": Brett's daughter makes sense to this one but its not the right timing so that's most likely wrong.

8. "Eugene kept a list": This one isn't known for sure, but my guess since Eugene isn't that common of a name is that it is supposed to be Eugene Reynolds of The Rezillos.

9."Mugger was security": Mugger was the roadie from Black Flag, he was also in the band Nig Heist and he worked at SST.

10. "Mary she kept her purity": Mary Harron, news reporter/publisher, possibly sarcasm with the line here.

Eugene starred in the movie The Decline Of Western Civilization, which was pretty much a punk movie, and he was pretty involved in the punk scene.

GG is Greg Ginn. Black Flag was really the first LA hardcore band, and they encouraged chaos at their shows. All the punks hated it and though they were too violent.

Mary is possibly Mary Rat, one of the plunger sisters who were pretty involved in the scene.

Laurie might be referring to Lori Lightning who was a groupie, but all I have to support that is name matching.

If you can't tell, this is about reflecting on the early L.A. hardcore scene; misfits finding a community together.
Billy - Brett Gurewitz
Jack - Jack Grisham from TSOL
Milo - Milo Auckerman from the Descendents
Tom - Tom Clement, Brett's friend
Mugger - Black Flag roadie and singer for the Nig-Hiest
Rodney - DJ from LA
Eugene - Skinhead feature prominently in "Decline of the Western Civilization"
GG - Not GG Allin, since he was from Conneticut or New Hampshire, but possible Greg Ginn (since there were a number of riots at Black Flag shows).

Tom (Clement) took his life in his mother's car
Milo (Aukerman) went to college but you knew about that
Rodney (on the ROQ) played our records
GG (Allin) started riots
Jack (Grishman) wore a skirt but he knew how to scrap
Billy (Gnosis/Gurewitz))went to county on a class one possession
Mugger (the Black Flag roadie) was security

When Brett says "Jack wore a skirt but he knew how to scrap", he is referring to Jack Grisham who is the singer of T.S.O.L. Grisham used to come out onstage wearing a skirt in response to the hardcore fashion of LA city punkers.

You don't belong, to me it sounds like some kind of memoir or a letter that says something like 'hey.. remember the good ol' times? The lines "Hey you, is there something worth belonging to? We've been here all along like a confederacy of the wrong and I confess it could be prejudice but to you i dedicate this song" back it up as well. On the album lyrics there's a bottle with the word 'poison' on it.. i know its a far stretch, but it kind of seemed to me as if this were a letter Greg would write to Brett to kind of help him realize who his friends were and to keep his head on straight from all the stuff he was going through. "just ones like us will never belong" As far as the people mentioned.. they are probably people they hung out with or saw at shows regularly, who knows. Rodney was from KROQ from "rodney on the roq" who cut their records on the air and got them exposure.

This is more of an autobiographical song, like a quick revision of their close friends' and acquaintances' lives, but again it deals with a recurrent theme: this question of not belonging to a certain scene or social group, but still accomplishing one's goals. Greg (though I think this is a Brett song) has always stated how an outcast he used to be when he moved down to LA... But still he managed to achieve his target; he formed a band and released a lot of records. Yet, that is not their ultimate aspiration ('and can it be found in a record store, will it's not there anymore'). They just set the list of other friends' deeds and place them all in the same level, with no jerarquization. They were all part of a 'confederacy of the wrong' (wrong for the outsiders, the mass, that is) and dedicate the song to all these people like you and me who maintain against the grain, don't belong (to the mass), but belong to somewhere else, less known for the average.

As far as the different names, I know for sure like you have all said that Tom is Tom Clement, who is mentioned in Along the Way ('like Tommy you are free') and also gives the alternative name for the song Give You Nothing... Anyway, I don't understand why they have to mention that particular fact. I mean, didn't they have a better memory of him?

Milo is Milo Auckerman. 'Milo went to college but you knew about that'. We know it because of the name of that album released by The Descendents, but Milo did go to college after he left the band. He is a good friend of Greg and Brett, and shared with the former their passion for Biology.

Rodney was the guy at KROQ who played first their EP Bad Religion.

Jimmy I have no idea about... Laurie neither... But just in case, do they happen to be friends with Laurie Anderson?

Jack a vague guess could be Jack Grisham (TSOL singer). He is a good friend of Brett, who played guitar in that Jack's just-one-song (Somebody to Love?) solo band project called Gentleman Jack Grisham (featured in the Punk o Rama IV). Interestingly, there is another Jack mentioned in Evangeline ('hey Jack, get back, in fact don't do that').

Billy sS without doubt Brett himself. Apart from the songs Billy Gnosis and Billy dealing with his problems with drugs, there is this great article on LA Weekly Magazine where Brett retells with full details the last time when he was caught red handed shooting crack by the police and after going to jail we went on rehab. He said that it was his fear of staying in jail more than his serious chances of death that made him go under treatment.

Wendy, Eugene, Mugger and Mary, again I have no idea about.

I do know that the people in this song are definitely real. Unfortunately, I'm not familiar with all of the people, but here are the ones I know for sure:
Tom is indeed Tom Clement. The song 'Best For You' is subtitled 'Tom Clement.' Brett once said that Tom was a friend of his who committed suicide (hence the line 'Tom took his life in his mother's car.')

Milo... remember the Descendents record, 'Milo Goes To College'?

Rodney is a disc jockey from the famous California radio station KROQ. He had a show called 'Rodney on the ROQ' and when BR first started playing, he played their records.

Billy is Brett Gurewitz. Recall the song 'Billy' which is all about Brett's battle with substance abuse. The line 'Billy went to county on a class one possession' refers to the time he was caught with ten balloons of heroin and was ordered by the court to go to rehab.

Billy is an alias for Brett, so the possibility exists that Brett is using aliases for all these people. That kind of fits with the whole Beatnik sensibility, using real experiences to create semi-fictional characters.

This one of those 'memories of the good old days' punk rock songs that older bands write.
Milo is obvious, Mugger was Black Flag's roadie, and Billy is probably a reference to Brett.

I assume all the names in it refer to real people. Tom I can only assume is Tommy Clement (sung about in Along the Way), Milo.. well Milo Auckerman. Missy.. no idea who that is. Jimmy... I dunno, could be Jim Lindberg? He's a pretty crazy guy, and I know he's worked with BR before. Laurie... I'm thinking Laurie Vitt, used to teach Greg, teacher type.. quiet. Wendy - was hoping one of Brett's kids was called Wendy.. but nup, so no idea. Eugene, Muggger and Mary, I don't get them either.
