Which band name did John Lennon use that was named after his old school?

The Quarrymen (also written as "the Quarry Men") are a British skiffle/rock and roll group, formed by John Lennon in Liverpool in November 1956, which eventually evolved into the Beatles in 1960. Originally consisting of Lennon and several schoolfriends, the Quarrymen took their name from a line in the school song of Quarry Bank High School, which they attended.

Calderstones School is an English comprehensive school located opposite Calderstones Park on Harthill Road in the Liverpool suburb of Allerton.

The school was founded in 1921 as Quarry Bank High School for Boys and its first intake of 225 pupils was on 11 January 1922. The first headmaster of the school was R. F. Bailey (an old Etonian). He formed the school on the principles of public school houses. Subsequently, the first year boys' house was named Bailey.

The school has several notable pupils, including founding Beatles member John Lennon.
