I've actually gotten up at a blues jam with Mike IIRC... he plays in various blues and shred bands in and around ATL, Stuck Mojo is another one that comes to mind.
He also does jem-Fest every year. Killer player!
I just notice something... if you are talking about this bassist:
I think that he was playing with "the Duke" as well on that last gig with Mike. One of the 6'er's that he had was a Converted Yamaha TRB Headless bass... He supposedly did it himself. It came out great and is really killer sounding. Was he playing a 4 or a 6 headless in Wales?
