I went and saw these guys last night and they were incredible. Their name is "The Dave Matthews Cover Band" and their website is www.thedmcb.com. They had the normal 5 members (guitar/singer, bass, sax/horn/etc., violin, and drums) and they sounded exactly like them it was creepy (check out some samples on their website. They played for around 3 hours and 25 minutes with about a 20 minute break half way through. Here are all the songs i remember:
#41
watchtower
ants marching
best of whats around
crush
everyday
grey street
jimi thing
minarets
so right
so much to say
anyone seen the bridge
too much
tripping billies
two step
what would you say
when the world ends
where are you going
you never know

And in case you think its cheap that they make money off this, the guy (dave) said that 60% of their profits go to the Bama Rags Foundation, dave's charity.

Not sure we need a DMB cover band in the world...their music doesn't really need a legacy. Glad you enjoyed it though
