Dave Matthews' political mindset fits into the category of who gives a f*** what he thinks, I certainly don't.
And in terms of groups to pay dollars to go see, I can count on my one hand and have a finger or two left over. They just are not worth seeing live for the dollars they want.
And heck, after you see Mick Jagger in his hay day, does anyone else remotely come close? I was never big on the Rolling Stones, but I went to a concert in 78 or 79 at the Superdome in New Orleans which had Van Halen, The Doobie Bros, and The Rolling Stones. I went to see the Doobies, one of my favorite groups, and it was a great concert. But I would never have imagined how entertaining Mick Jagger was. It was a great concert.
