I didn't realize it was possible to bugger a football...quite a mental image, that one.I did notice on Dylan's movie "Hard To Handle" (an Australian tour in the 80's with Tom Petty and the Heartbreakers backing him) that he had a really strange, crouching posture while strenuously playing the guitar...fantastic performance of "It's All Right Ma" on acoustic guitar.
Then too, at the Dylan/Joni Mitchell concert a couple of years back in Toronto he spent a lot of time standing with his feet well apart but his knees almost touching...weird...I've tried doing that as an experiment and it's damned uncomfortable.
