Lennon started a skiffle group that was very briefly called the Blackjacks, but changed the name before any public performances. Some accounts credit Lennon with choosing the new name; other accounts credit his close friend Pete Shotton with suggesting the name. The Quarrymen played at parties, school dances, cinemas and amateur skiffle contests before Paul McCartney joined the band in October 1957. George Harrison joined the band in early 1958 at McCartney's recommendation, though Lennon initially resisted because he felt Harrison (still only 14 when he was first introduced to Lennon) to be too young. Both McCartney and Harrison attended the Liverpool Institute.
