John Lennon (in 1980) - "His song... I might have done something."
Paul McCartney (in 1994) - "'What You're Doing' was a bit of filler. I think it was a little more mine than John's... You sometimes start a song and hope the best will arrive by the time you get to the chorus, but sometimes that's all you get, and I suspect this was one of them. Maybe it's a better recording than it is a song, some of them are. Sometimes a good recording would enhance a song."
