In an MTV 120 Minutes interview from 1993 Lewis Largent asks Greg and Brett about Eddie Vedder's collaboration. Greg explained that Eddie sang backup on American Jesus and Watch It Die. Those are the only two places on that record that Eddie sings. In Watch it Die he sings the second verse, from "I saw a man" to "put to sleep". In American Jesus, only backing vocals. Greg said they came up with that idea because Eddie used to sneak backstage at all of the BR shows to try to meet the band, and that's how they met him. He used to come check out BR in San Diego, where he lived, long before Pearl Jam came to be. When they were doing the background vocals overdubbing for Recipe For Hate in L.A. it just so happened that Eddie was in town so they had him on the phone and invited him over. So he said ok and cruised over in his Mazda truck, but it was very spontaneous, they hadn't planned anything beforehand. On an early promo photo of Pearl Jam, around 1990-1, Eddie Vedder was wearing a Bad Religion T-shirt. Greg also says he would like to record a whole album with Eddie someday: "I would like to put together something out of the ordinary, but still really good". When Ten came out, BR went to Europe and played some shows with Pearl Jam opening for them in Germany. Jay: "We hung out and were all getting goofy. You know how when you sit down with someone, and your jokes are all the same, you have the same sense of humor, you do things that are similar? You just kind of connect. At the second show we played with them, he and I decided to go onstage, and see who could punk out the most. But I told him, "You can't climb up anything because I can't when I'm playing bass, so you have to do it at ground level.' He goes out there and does his thing, and I think, 'Whooo, it's going to be hard to top that one.' Then I go out, and during the first song I'm swinging my bass around and my strap breaks. My guitar had such momentum that it went flying to the other side of the stage, landed on the ground and went 'Whhhhooooo.' I just stared at it for a moment, stared at the audience, then looked at Ed. He just shouted, 'You Win!'". When they played Seattle Eddie went onstage with BR and sang a song, and people were flipping him off and spitting on him 'cause of course he's so popular he's hated by many self-righteous punkers.
