Where once Jones played multiple instruments on many tracks, he now played only minor roles on a few pieces. Jones's last formal appearance was in the December 1968 "The Rolling Stones Rock and Roll Circus", a part-concert, part circus-act film organised by the band. It went unreleased for more than 25 years because Jagger was unhappy with the band's performance compared to others in the film such as Jethro Tull, John Lennon, the Who, and Taj Mahal. Commentary included as bonus material indicated that almost everyone at the concert sensed that the end of Jones's time with the Rolling Stones was near, and Roger Daltrey and Pete Townshend of the Who thought it would be Jones's last live musical performance.
