Yes, it's true, Queen is joining up with Adam Lambert for a North American tour. The three performers will hit the road beginning June 19 in Chicago, IL. The tour will wrap up on July 20 in Washington, D.C.
The trio has recently been increasing their amount of touring activity. In 2011 and 2012 they toured together in Europe, and last September they performed at the iHeartRadio Music Festival.
On a side note, I'm very happy to admit I was wrong about the likeliness of this happening. A few years ago, I wrote a post about bands that should get back together for a reunion tour. I regarding as this to be an unlikely thing for Queen due to not much happening in terms of getting Lambert on board. Well, now he is on board, and they are going on tour.
