Maxwell's Silver Hammer
The length of time it took to record the song created tension between the Beatles. Paul McCartney said: "The only arguments were about things like me spending three days on Maxwell's Silver Hammer. I remember George saying, 'You've taken three days, it's only a song.' - 'Yeah, but I want to get it right. I've got some thoughts on this one.' It was early-days Moog work and it did take a bit of time".
