DISPATCH sells out 3 nights @ MSG, adds Webster Hall show

The weirdest thing happened recently (well, not that weird). A band called Dispatch sold out three nights in a row at Madison Square Garden, and I realized I had never even heard of them. I guess I slept through that part? Anyway, they added a fourth show at Webster Hall that goes on sale next week via Ticketmaster Auction (thx Matt). Are they friends with O.A.R.?
