How Billy Preston Helped the Beatles "Get Back"
McCartney came up with the idea that the band should perform a live or taped television broadcast in front of an audience. A venue could not be agreed upon, so just to get things rolling, it was suggested that they at least start rehearsing at Twickenham Studios. The rehearsals were filmed for potential inclusion in a television broadcast or a proposed “Beatles at Work” film.
On January 10, the rehearsal came to a crashing end when McCartney and John Lennon had a bitter argument and Harrison, fed up with the bickering, walked out of the studio. He returned five days later and said he was leaving the group unless the television show idea was dropped. He wanted to work on an album, and he wanted to bring along a friend.
