unknown. Magical Mystery Tour was broadcast in the UK on BBC1 on 26 December (Boxing Day), but in black and white rather than colour. It was the Beatles' first critical failure. As a result of the unfavourable reviews, networks in the US declined to show the film there. Beatles' management team member Peter Brown blamed McCartney for its failure. Brown said that during a private screening for management staff, the reaction had been "unanimous ... it was awful", yet McCartney was convinced that the film would be warmly received, and ignored Brown's advice to scrap the project and save the band from embarrassment.

It was shot over a four-week period in January 1969, and includes an unannounced rooftop concert by the group, which was their last public performance. The documentary — originally intended to be a chronicle of the evolution of an album and the band's possible return to live performances — captured the prevailing tensions between the band members, which
