Does anyone know John's shoe size?

I saw an interview once where Ringo was asked each Beatle's shoe size, and he told the interviewer quite seriously that he wears a size seven, and Paul and George take size eight. But when they got to John, Ringo laughed and сказал(-а) "Thirty-two" - so I kind of got the idea that John's feet are significantly larger than the others'. Also in "I'll Cry Instead" John references having big feet, and it's even mentioned in the Beatle Cartoons! Maybe John takes a size eleven или twelve? Does anyone know?
