18. "Coming Up"
As the Seventies drew to a close, McCartney retreated to his Scottish farm and had some fun with a tape machine. "I got into all sorts of tricks, and I can't remember how I did half of them," he said of this tune, a hyper-caffeinated groove with quirky sped-up vocals. Among the song's many fans was Lennon – "Coming Up" reportedly inspired him to make music again.
