On this day in music history: January 2, 1969 - The Beatles begin rehearsals at Twickenham Studios in London for a proposed live concert and album of new material written by the band, which is also being filmed by director Michael Lindsay-Hogg. However, things will not go well when unresolved personal and business issues that arise during sessions for “The White Album” resurface and intensify. George Harrison quits the band (temporarily) eight days into rehearsals. Following this incident, rehearsals and filming move to The Beatles’ offices/studio on Savile Row in the Mayfair district in Central London. The sessions continue for another ten days, concluding with the now famous rooftop concert on January 30, 1969, with one final day of recording in the studio on January 31, 1969. The recording sessions produce over thirty hours of music and film, which are shelved for over a year, when no one can face the task of editing and mixing. After Allen Klein is brought in as the band’s manager, the project is revived, and the recordings and film are released as the album and film “Let It Be” in May 1970.
