Beatles (n.)

seminal rock and pop group formed in Liverpool, England; named as such 1960 (after a succession of other names), supposedly by then-bassist Stuart Sutcliffe, from beetles (on model of Buddy Holly's band The Crickets) with a pun on the musical sense of beat. Their global popularity dates to 1963.
