Intro Differences

In the three recorded versions of the song (New Maps Of Hell Deluxe Edition, 30 Years Live, and The Dissent Of Man), all the introductions are different. 

Jay:"I don't know. It just kind of is. In fact, the live album intro is different from the way we were playing it by the end of that tour. We changed it like three times during the tour. The shows at which we recorded the live record were the first 4 or 5 shows." ^[1]
