Perhaps the most influential musical group of all time, the Beatles make their last public performance on this day in 1969, giving an impromptu concert on the roof of their London recording studio. Neighbors complained about noise, and police broke up the concert. John Lennon closed the performance announcing, "I'd like to say thank you very much on behalf of the group and myself and I hope we passed the audition." In April 1970, Paul McCartney formally announced the group's breakup. The Beatles, who led the rock-music movement called the "British Invasion," revolutionized popular music around the world and achieved unprecedented popularity.
