From Bob Dearborn's The Olde Disc Jockey's Almanac. On this day in history, 45 years ago...
December 11, 1968…At Wembley studios in Middlesex, England, the Rolling Stones filmed the "Rolling Stones' Rock and Roll Circus" TV special, featuring performances by John Lennon, Eric Clapton, the Who, Jethro Tull, and Marianne Faithfull. Filmed in a circus tent and with actual circus people, the show never aired, supposedly because the Stones thought the Who's performance upstaged them. The special was finally released in 1996.
