Elvis Presley's explosion onto the rock music scene inspired a 16-year-old Lennon to create the skiffle band called the Quarry Men, named after his school. Lennon met Paul McCartney at a church fete on July 6, 1957.

He soon invited McCartney to join the group, and the two eventually formed one of the most successful songwriting partnerships in musical history.

McCartney introduced George Harrison to Lennon the following year, and Harrison and art college buddy Stuart Sutcliffe also joined Lennon's band. Always in need of a drummer, the group finally settled on Pete Best in 1960.

The first recording they made was Buddy Holly's "That'll be the Day" in 1958. In fact, it was Holly's group, the Crickets, that inspired the band to change its name. Lennon would later joke that he had a vision when he was 12 years old—a man appeared on a flaming pie and said unto them, "From this day on, you are Beatles with an 'A.'"

The Beatles were discovered by Brian Epstein in 1961 at Liverpool's Cavern Club, where they were performing on a regular basis. As their new manager, Epstein secured a record contract with EMI. With a new drummer, Ringo Starr (Richard Starkey), and George Martin as producer, the group released their first single, "Love Me Do," in October 1962. It peaked on the British charts at No. 17.

Lennon wrote the group's follow-up single, "Please Please Me," inspired primarily by Roy Orbison, but also fed by Lennon's infatuation with the pun in Bing Crosby's famous lyrics, "Oh, please, lend your little ears to my pleas," from the song "Please." The Beatles' "Please Please Me" topped the charts in Britain. The Beatles went on to become the most popular band in Britain with the release of such mega-hits as "She Loves You" and "I Want To Hold Your Hand."
