Cover art for Sweet Sister Ray lyrics by Velvet Underground, The

Stream of consciousness intro to "Sister Ray". It's about the title character, I believe a crossdressing heroin dealer. Lou would just make it up as he went along. Similar lyrics appear on the lost song "Sweet Rock 'n' Roll", a.k.a. "Sister Ray Part 2". There was also a "Sister Ray Part 3". Both sounded totally different from the original, as does "Sweet Sister Ray". Part 2 was dolorous, kind of "Venus in Furs"-ish according to Lester Bangs, part 3 starting totally insane and slowing down slowly but surely until it started to sound like the original.
