"Cocksucker Blues"
Rolling Stones/Robert Frank

(YouTube.com)

Type "cocksucker blues" into YouTube and one of the first selections is a two-minute clip of the Rolling Stones getting dressed before a show. While a young Keith appears stoned and aloof, Mick hams, showing the world his skinny ass. The soundtrack features an unreleased demo of a mournful Stones piano ballad. The grainy black-and-white footage is from the holy grail of Stones bootlegs, the unreleased documentary Cocksucker Blues. Directed by Robert Frank, the movie chronicles the Stones drug-fueled North American tour in support of Exile on Main Street. Incidentally, the Jagger-penned unreleased song, "Cocksucker Blues," can also be found on YouTube.
