The Quarrymen
After McCartney's poor performance on lead guitar at the Conservative Club, the group needed another guitarist to accommodate their new rock-focused repertoire; McCartney recommended his school friend George Harrison. Harrison first saw the group perform on 6 February 1958 at Wilson Hall, where McCartney introduced him to Lennon. Harrison subsequently auditioned for The Quarrymen in March at Rory Storm's Morgue Skiffle Club, playing "Guitar Boogie Shuffle". Lennon thought Harrison (having just turned 15) was too young to join the band, so McCartney engineered another meeting on the upper deck of a Liverpool bus, where Harrison played "Raunchy" for Lennon. After McCartney's constant advocacy, Lennon allowed Harrison to join the Quarrymen as lead guitarist. Harrison's entry into the Quarrymen shifted the group even more away from skiffle, in addition to ending Lennon's use of banjo chords. Around this time, John Duff Lowe, another school friend of McCartney, joined the group on piano.
