That's a great story. My equivalent is that years ago I was playing at a jazz funk jam in Cambridge with a drummer mate of mine. A guy gets up and asks if he can play a bit of guitar. No problem of course. Anyway, this bloke is seriously good with such fantastic feel and groove. Afterwards I said to my mate 'He's a bit good. Do you know if he's in a band?' 'Yes' replied my mate. 'He's Rob Harris out of Jamiroquai.'
