It was 51 years ago today (December 15th, 1969) that John Lennon and Yoko Ono assembled their legendary Plastic Ono Supergroup for a historic performance at London's Lyceum Ballroom. The event was part of UNICEF's Peace For Christmas concert, which featured a number of other performers including the Hot Chocolate Band, Jimmy Cliff, and the Rascals, among others.
Lennon's backing band featured George Harrison — marking the final time the pair ever shared a stage together — Eric Clapton, Keith Moon, bassist Klaus Voormann, Lennon's primary drummer at the time — and future Yes sticksman Alan White, Billy Preston, Delaney & Bonnie and their backing band — which included drummer Jim Gordon, keyboardist Bobby Whitlock, and bassist Carl Radle — who the next year would for Derek & The Dominoes with Clapton — and horn players Jim Price and Bobby Keys who would soon move on to greener pastures as part of the Rolling Stones' touring band.
Lennon led the ensemble through his and Yoko's current single — “Cold Turkey” which was extended to nearly seven minutes. The band also performed Yoko's B-side “Don't Worry Kyoko (Mummy's Only Looking For Her Hand In The Snow) which topped out at over 15 minutes.
