When Rob Reiner directed the classic 1984 mockumentary This is Spinal Tap, starring Christopher Guest, Harry Shearer and Michael McKean as members of an impossibly dumb, impossibly pretentious British rock band, he probably never imagined the group would still be going strong 25 years later. "It's going to be one tour inside another tour wrapped in an enigma inside a travesty," Guest told E! about their "Uwigged & Unplugged" tour, which kicks off April 17 in Vancouver, "We're gonna destroy hotel rooms," Guest added, before Shearer jumped in to correct him: "Actually, at our age, we're gonna hire people to destroy hotel rooms for us." But fans shouldn't get too excited. There won't be much fanfare, or smoke and mirrors. "No smoke," McKean said. "One mirror. Just backstage."
