Crippling stage fright almost prompted Sir Paul McCartney to quit The Beatles.
The All You Need Is Love hitmaker had played the wrong guitar chords during one of the band's first-ever gigs and MCCartney admits the mistake made him consider abandoning his dreams - because he worried he might never overcome his jitters.
He tells Britain's Daily Mirror newspaper, "The first time we ever played - pre-Beatles - I screwed up. So I never played lead guitar again. When the Beatles did Wembley (Arena) for the first time (in 1963), I felt sick. I thought, 'I’ve got to give this up'."
