Jimi Hendrix was so excited after the UK release of Sgt. Pepper’s Lonely Hearts Club Band in 1967 that he opened a set at London’s Saville Theater with his own, Hendrix-ified rendition of the song just three days after the album's release. In the audience: McCartney and George Harrison.
McCartney considered it to be a compliment and one of the great honours of his career.
