Here we are in early 2007 - and folks, we have a Summerfest show announcement - none other than Toby Keith who will close Summefest in Milwaukee on July 8, 2007 at the Marcus Amphitheater.
From here it's conjecture...Van Halen with David Lee Roth and The Police reunion tour seem to be tops on the radar.
Regardless of your taste, there is usually a headliner which is appealing. If you find yourself needing tickets, I would check out Ticket King in Milwaukee (home of Summerfest). Their office is almost walking distance from the Summerfest grounds and the people there are super nice and informative....even when it's Toby Keith you want to see (just kidding!)
