Paul McCartney said, “Well, he’s like a joke… about this fellow who cured everyone of everything with all these pills and tranquilizers, injections for this and that; he just kept New York high. That’s what ‘Doctor Robert’ is all about: just a pill doctor who sees you alright. It was a joke between ourselves, but they go in in-jokes and come out out-jokes because everyone listens and puts their own thing on it, which is great… You put your own meaning at your own level to our songs and that’s what’s great about them.” Paul also said, “John and I thought that was a funny idea, the fantasy doctor who would fix you up by giving you drugs. It was a parody on that idea. There was a fashion for it. Change your blood and have a vitamin shot and you’ll feel better.”
