As lead guitarist for the Beatles, George Harrison provided the band with a lyrical style of playing in which every note mattered. Harrison was one of millions of young Britons inspired to take up the guitar by British skiffle king Lonnie Donegan's recording of "Rock Island Line." But he had more dedication than most, and with the encouragement of a slightly older school friend -- Paul McCartney -- he advanced quickly in his technique and command of the instrument. Harrison developed his style and technique slowly and painstakingly over the several years, learning everything he could from the records of Carl Perkins, Duane Eddy, Chet Atkins, Buddy Holly, and Eddie Cochran. By age 15, he was allowed to sit in with the Quarry Men, the Liverpool group founded by John Lennon, of which McCartney was a member; by 16 he was a full-fledged member of the group.
