I saw Dave Van Ronk, at the Bottom Line, May 29, and he sang "Cocaine". He sang the words posted here.I play my version of his version of the song, in fingerstyle, that I learned back in the middle 60s. He says he learned it from Rev. Gary Davis.
Back in the 60s drugs were a more innocent thing, and there were fewer consequences, or so we thought. Nobody who sings this song today is advocating drug use, but the song is a lot of fun to sing and play, especially when I ham it up, ala Dave Van Ronk!
Thanx, EZR
