John Lennon (in 1980) - "That's Paul with some contribution from me on lines, probably. We put in the words 'turns me on.' We were so excited to say 'turn me on' --you know, about marijuana and all that... using it as an expression."
Paul McCartney (in 1994) - "This was my attempt at a bluesy thing... instead of doing a Little Richard song, whom I admire greatly, I would use the (vocal) style I would have used for that but put it in one of my own songs."
