Cocksucker Blues (1972)
This fly-on-the-wall documentary follows the Rolling Stones on their 1972 North American Tour, their first return to the States since the tragedy at Altamont. Because of the free-form nature of filming, Cocksucker Blues captured band members and entourage members taking part in events the Rolling Stones preferred not to publicize. It can only legally be screened with director Robert Frank in attendance. The title of the film is the same of that of a Rolling Stones song (aka Schoolboy Blues), which was written to complete the band's contractual obligations to Decca Records and specifically to be unreleasable.
