I'm Waiting for the Man (off The Velvet Underground and Nico / Live at Max's / 1969 / Live MCMXCIII / Peel Slowly and See / Final V.U. / The Quine Tapes)
and
Heroin (off The Velvet Underground and Nico / 1969 / Live MCMXCIII / Peel Slowly and See / The Quine Tapes)
I'm Waiting For The Man, because along with Venus In Furs, it was the hook that got me interested in the Velvet Underground in the first place. I love Heroin though, but it just doesn't have the addictive quality that IMFTM has.
