I wonder if they'll only be playing Cheap Trick and Deep Purple songs, or if they'll play their own bands' music, too? It would be interesting to see DeLeos + Sorum together playing a couple STP or VR songs. Like a mini-tribute to Scott in the show. Plus you have Corey Taylor there, who regularly covers both STP and VR with Camp Freddy/Kings of Chaos.
I don't think it's likely, but it would be a hell of a trip to see the DeLeos playing a VR tune.
