The Quarrymen and founding of The Beatles
The Beatles were officially formed in 1960, but their origins trace back to 1957 when 16-year-old John Lennon started a skiffle group called The Quarrymen in Liverpool.
Sir Paul McCartney joined later that year, followed by George Harrison in early 1958.
After several name changes and lineup shifts, the group became The Beatles in August 1960, solidifying their classic lineup with the arrival of drummer Ringo Starr in 1962.
