When I’m Sixty-Four first appeared on the Beatles’ 1967 album, Sgt. Pepper’s Lonely Hearts Club Band. Despite the song’s appearance relatively late in the Beatles’ discography, it was one of the first songs that Paul McCartney wrote, at the age of 16. When the song was finally recorded in 1966, Paul McCartney felt it was too slow and turgid. George Martin simply solved the problem by speeding up the tape and raising the pitch by one semitone.

This version of When I’m Sixty-Four is arranged as a duet for two Clarinets.
