In March 1957, John Lennon, then aged sixteen, formed a skiffle group with several friends from Quarry Bank High School in Liverpool. They briefly called themselves the Blackjacks, before changing their name to the Quarrymen after discovering that a respected local group was already using the other name. Fifteen-year-old Paul McCartney joined them as a rhythm guitarist shortly after he and Lennon met that July.
