Sam, can you play Jean's Reel like Phil Cunningham? Can I join you? That would be my choice too, I thought of it before I opened the thread, & you've beaten me to it :-).
I agree, Colin, that you don't NEED 'show off' tunes but don't you get a buzz when you've played a difficult tune well? Or when the audience get a buzz off you doing it? Not arguing, just discussing!
