Now, the two bands have agreed to team up for a string of dates. And Michaels, who said iconic glam rockers the New York Dolls will support them on tour, is ecstatic about the collaborative gigs to mark their joint anniversaries.
He tells CNN talk-show host Piers Morgan, "Huge, it's coming, are you ready? All that stuff I talked about is coming. It will be the tour of the summer. That's what the promoters are calling it, that's what I'm calling it.
"It will be Poison's 25th anniversary tour along with Motley Crue's 30th anniversary tour and a very special guest will be coming with us on the road. Poison and Motley Crue have never toured together. It will be the rock tour of the summer. The New York Dolls (are the special guests). They're a great band and it will be their 40th anniversary."
