Yeh, and the other excellent guitarist on the video is Warren Haynes, well known as the frontman of Government Mule, another cracking Southern Rock band.
Personally if you join a band you need to commit and not join with a half arsed attitude, I would not entertain anyone with the idea of trying a couple of gigs to see if they liked it.
Totally agree, I cannot see how any pub can manage or police SD, especially if a live band is performing, some of the pubs we play, we are lucky to get three feet away from the other band members.
