The Quarrymen
Omori works often with Sophie Vaughan, cellist and vocalist. Daughter of Ivan Vaughan, was a boyhood friend of John Lennon, and later schoolmate of Paul McCartney. He played bass part-time in Lennon's first band, The Quarrymen, and was responsible for introducing Lennon to Paul McCartney at a community event (the Woolton village fête) on 6 July 1957, where The Quarrymen were performing. McCartney impressed Lennon, who invited McCartney to join the band, which he did a day later. This led to the formation of Lennon and McCartney's songwriting partnership, and later of The Beatles.
