I've not heard of Michael Hedges - I'll check him out when I've got an internet connection back at home!
It's be really nice if it was a small, intimate show like the one I saw. Andy seemed like a really nice bloke, incredibly humbled by the people who'd gone to see him, even though there was probably less than 100 people there. It was a really nice evening!
I know I'm sig-pimping him right now, but if you're into that sort of thing and haven't listened already, Newton Faulkner is a bit Mckee-esque - does the whole body-tapping thing, but he sings as well. The album's definitely worth a listen.
