Paul McCartney helped Lennon set up his "home studio" in the attic at Kenwood, with its set of daisy-chained tape recorders; this he used for song demos, or sometimes experimental music and effects. Boyhood friend Pete Shotton would visit on weekends (during the week he ran a supermarket on Hayling Island, owned by Lennon and George Harrison), and the two collaborated on experimental recordings, creating tape loops and sound collages. (Some of these were later used in Two Virgins; Lennon's first collaboration with Yoko Ono.)
George Harrison had an Ampex four-track recorder, which he used for song demos at Kinfauns (his home in Esher); sometimes all The Beatles were present, particularly when they began work on the "White Album".
Recording Vocal Comedy
John Lennon
No. In fact, they had a strict rule that no wives or girlfriends were even allowed to attend recording sessions. John Lennon ultimately broke that rule with Yoko Ono, but she was not welcome either.
it took place in 1996
It didn't. McCartney, Harrison and George Martin were annoyed by Yoko Ono's presence in the recording studio (and especially her speaking up during sessions), but many other factors led to their breaking up.
John Lennon, who also played lead guitar on the recording.
No, they never did. A few years before John Lennon's death, they were considering collaborating again, but sadly it never happened. :( The closest thing to a Lennon-McCartney recording was "The Ballad of John and Yoko" on which John and Paul played all the instruments.
John Lennon
John Lennon, as plainly seen in the live video of the Beatles recording the song.
No, John Lennon is not single.
Yes and in fact the members of both groups became friends. Micky Dolenz and Paul McCartney and Michael Nesmith and John Lennon in particular palled around with some frequency in 1967-8 and Mike was invited to help out in some early 1967 recording sessions with The Beatles.
John did change his name from John Winston Lennon to John Ono Lennon
