The three are teaming up for a summer outing titled .

The arena-sized trek looks to kick off May 10 in Las Vegas with dates stretching into July. Additional shows are expected to be announced shortly, probably filling in the gaps in June. Tickets for a few shows are already on sale, with more hitting the outlets April 5.

“Journey, Styx, and REO Speedwagon are all heavyweights in the history of American rock and roll music. We are thrilled that VH1 Classic will be presenting their summer tour and updating our viewers on the tour’s progress,” Eric Sherman of VH1 Classic said.

So, to refresh any graying memories, here’s who’s in the bands these days: Journey is Neal Schon, Ross Valory, Jonathan Cain, Steve Augeri, and Deen Castronovo; REO Speedwagon is Kevin Cronin, Neal Doughty, Bruce Hall, Dave Amato, and Bryan Hitt; and Styx is Tommy Shaw, James “JY” Young, Glen Burtnik, Todd Sucherman, and Lawrence Gowan.

Original Styx bassist Chuck Panozzo will make some surprise appearances in select cities.
