A previously-unreleased recording outtake was shared via John Lennon's official YouTube account, taken from the upcoming John Lennon: Imagine: The Ultimate Collection which will hit stores on 9th Oct.
The video description states, "Imagine you are at the Lennon’s home, Tittenhurst Park in Ascot, England. It's night. It's the last week in May in 1971 and you are their special guest, sat in a chair in the very centre of their recording studio, Ascot Sound Studios."
In the video, Lennon and his Beatle bandmate, George Harrison can be seen jamming with the Plastic Ono Band. The video description continues, "John Lennon is sat in front of you, teaching the musicians one of his latest compositions. He is talking and singing and playing the same wood-finish Epiphone Casino electric guitar he played on 'Revolution'.
A bearded George Harrison is in front of you, to the right, playing electric slide on John's pale blue Fender Strat. Just behind you and to your right, Rod Lynton with Ted Turner from Wishbone Ash are strumming chords on twelve string acoustic guitars, and directly behind you to the right, John and George's old friend Klaus Voormann is playing his deep hand-painted Fender Precision bass.
"Behind you to the left, Alan White (who would later join Yes) is playing his Ludwig silver sparkle drumkit, and in front of you to the left, John Tout from Renaissance is playing chords on the Steinway upright piano, and to his right, Nicky Hopkins is improvising on the red-top Wurlitzer Electric Piano, literally days before he leaves for Nellcôte to play on Exile on Main Street with The Rolling Stones."
Watch them perform "How Do You Sleep" in the full video above.
