Doing the odd (well, not that odd :)) session in London during the late 60’s/early 70’s, I worked with a few good 'uns. Jimmy Page, Eric Clapton, Clem Cattini, Chris Spedding, among other lesser-known but equally able players. The producer would change things on the fly and none of these guys would turn a hair. And, to a man, all great guys to work with. I miss those days.
