John Lennon was just 17 when he formed his first band, The Black Jacks. The band was made up entirely of classmates at Quarry Bank Grammar School in Liverpool, and almost immediately after they started, they changed their name to The Quarry Men. They played skiffle music, a mixture of folk, jazz, and blues which was popular in England at the time.
In the summer of 1957, The Quarry Men were setting up for a performance in a church hall when another member of the band introduced Lennon to Paul McCartney, then a 15-year-old self-taught left-handed guitar player.
