So, while fans might have wondered how such a massive tour came together, in a new promotional video for the tour, Def Leppard frontman Joe Elliott and Journey guitarist Neal Schon consider it "Mission Possible."
Why? Because they want to do it!
In the promo, we see Elliott and Schon meeting up at the Live Nation headquarters to plot the summer tour themselves!
"We are gonna go everywhere," Elliot says while writing on the wall of a conference room.
Check out the spot above.
In a January announcement with Q104.3 New York's Jim Kerr, Schon and Elliott promised their co-headlining jaunt this summer would be the "tour of the year."
While the Live Nation-produced promo is a laugh, the two chart-topping rockers told Kerr at the time that a big reason the tour was happening was because the respective bands wanted to do it. And that goes a long way with management.
"We toured together in 2005, and it was just one of the biggest tours that we'd done since Hysteria, I think at the time. It was a fantastic tour," Elliot said. "Then we kind of—excuse the pun—went our separate ways (laughs)."
Def Leppard and Journey will take turns as to who closes the shows each night.
"You think about the catalog of songs that both bands have got; just close your eyes and make your own setlist up and it'll be about 80 percent correct, I'm sure."
But can they cram all their hits into each night?
"Yeah, I'll play them faster, just like the Ramones," Elliot joked.
The 58-city tour kicks off May 21 in Hartford, Connecticut. Get your tickets at LiveNation.com.
