At the time, The Beatles’ Let It Be had the highest debut on the Billboard Hot 100, beginning its chart run at No. 6. Paul McCartney first began to play around with “Let It Be” in the recording studio in between takes of “Piggies” in September 1968. Some months later, the song would be rehearsed at Twickenham Film Studios on 3 January 1969, where the group had, the previous day, begun what would become the Let It Be film. It was their final single before Paul McCartney announced his departure from the band.
