Lennon and McCartney on "You Can't Do That"

Not sure which interviews these snips came from...

YOU CAN'T DO THAT(Lennon/McCartney)

JOHN 1964: "I'd find it a drag to play rhythm all the time, so I always work myself out something interesting to play. The best example I can think of is like I did on 'You Can't Do That'. There really isn't a lead guitarist and a rhythm guitarist on that, because I feel the rhythm guitarist role sounds too thin for records. Anyway it drove me potty to play chunk-chunk rhythm all the time. I never play anything as lead guitarist that George couldn't do better. But I like playing lead sometimes, so I do it."

JOHN 1980: "That's me doing Wilson Pickett. You know, a cowbell going four-in-the bar, and the chord going 'chatoong!'"
