Sammy Hagar and his band The Circle will do a rooftop concert at the Las Vegas Paris resort on September 22. A couple of hundred guests will witness it up close on the roof's party deck, but the set will be and clear to the ear on much of the Strip. He'll follow that one-off concert with a short residency later in the fall at The Strat in Vegas that will include several special guests during its run. The 800 seat venue is being decked out in the style of the Red Rocker's Cabo Wabo Cantina in Cabo San Lucas, the scene of many wild Sammy Hagar birthday bashes in years past.
