Don't let Sandy fool you about his guitar playing, like Jack Elliot, Del McCourey, Peggy Seeger, and not a whole lot of others, his accompaniments are spot on, always complimenting the song being performed. It's called subtlety and can be a little more difficult to recognise unless you've been playing (and loving) the guitar for many years. A number of years ago I complimented Sandy on his guitar playing, and he said "grummph,mumblummmph!!?*" which I've come to know now as meaning "bullshit in a polite way". He probably thought I was just making conversation with the only other smoker at the festival (one of us has since quit) but were that the case I could have complimented his beautifully inlayed Laskin rather than it's player. Besides when I'm messing around at the 14th fret hunting for a chord..he's already found his.
