John Lennon (in 1980) - "That was one of the earliest heavy-metal records made. Paul's contribution was the way Ringo played the drums."
Paul McCartney (in 1994) - "I think the interesting thing is the crazy ending--instead of ending like the previous verse, we changed the tempo. We picked up one of the lines, 'My baby don't care', but completely altered the melody. We almost invented the idea of a new big of a song on the fade-out with this song... It was quite radical at the time."
