One of those coincidences that makes you wonder if they really are coincidences: after reading this thread for the first time yesterday, last night I saw Phil Beer sing Billy Joel's "Downeaster Alexa" (mentioned by George Papavgeris above). He did it in great style too - this was Phil's solo spot in the current Show of Hands tour. It took me by surprise because I've seen SOH twice before on this tour, and he did different songs on the previous two occasions - this one was by far the best of the three IMO.

Or maybe it isn't a coincidence after all, and Phil's a Mudcatter too? ;-) Unfortunately I didn't see Phil afterwards this time, or I would have asked him.
