Video: 'Cold Turkey/Don't worry Kyoko-Plastic Ono Band live at Lyceum Ballroom, London War Is Over 1969'

(Tuesday, December 16, 1969, approximately at midnight-12:40 a.m.) — John Lennon of The Beatles headlined the Peace For Christmas UNICEF concert tonight at the Lyceum Ballroom in London, performing as the Plastic Ono Band, which in this case, included fellow Beatle George Harrison.

Eric Clapton had shown up unexpectedly at the concert with nearly the entire Delaney & Bonnie and friends tour band, which also consisted of Harrison.

This, therefore, was the first time Lennon and Harrison had performed at a scheduled concert since The Beatles’ last show on Aug. 29, 1966 at Candlestick Park in San Francisco.

The performers also included Lennon’s wife, Yoko Ono, on vocals, Clapton and Delaney Bramlett on guitar, Bonnie Bramlett on tambourine, Klaus Voormann on bass, Alan White and Jim Gordon on drums, plus Billy Preston on keyboards, Bobby Keys on saxophone and Jim Price on trumpet.

Keith Moon took to the stage to hit White’s floor tom tom, and also present but not performing were the Bonzo Dog Band’s drummer Larry ‘Legs’ Smith and The Rascals’ drummer Dino Danelli.

Lennon later referred to it as the Plastic Ono Supergroup.

In front of a backdrop saying WAR IS OVER, the centerpiece of John & Yoko’s Christmas advertising blitz announced earlier in the day (see below), they played extended versions of “Cold Turkey” and “Don’t Worry Kyoko (Mummy’s Only Looking For Her Hand In The Snow).”

The entire show was recorded and part of their set was released on John & Yoko’s 1972 double album Sometime in New York City after overdubs were added to both “Cold Turkey” (a second lead vocal, electric piano by Nicky Hopkins and bass guitar parts by Klaus Voorman) and “Don’t Worry Kyoko (Mummy’s Only Looking For Her Hand In The Snow)” (new bass part) on Oct. 31, 1971, at Record Plant East in New York City.

Earlier in the day (Dec. 15, 1969), Lennon and Ono announced their anti-war Christmas advertising campaign that was launched in eleven major cities around the world beginning Dec. 16, 1969.

To coincide with the launch, huge posters and billboards were erected in 11 major cities proclaiming “War is over! If you want it. Happy Christmas from John & Yoko.”

The couple was interviewed about the peace campaign today at Apple Corps headquarters in Savile Row, London, for the Dec. 29, 1969, edition of the Dutch TV news magazine program Televezer Magazine on AVRO-TV.

Also on this busy day, a third Beatle, Ringo Starr, recorded (at Apple Corps headquarters) a contribution for the BBC’s festive charity appeals, in this case to help raise money for the British Wireless For The Blind fund (click here to listen).

The recording was aired on Christmas Day on Radio 1’s Kenny Everett’s Christmas Show at 10:00-10:15 a.m.
