Queen's Brian May and Roger Taylor will be at Madison Square Garden in New York this morning to announce they are doing a North American tour this summer with Adam Lambert on vocals. What we do know is that there are 19 dates in 18 cities - 12 in the U.S. and seven in Canada - with the majority of them being arenas, although there is one amphitheater and one theater.

This is Queen's first-ever tour of North America with Lambert following a one-off performance last September in Las Vegas, and a run of shows in Europe in 2012. They first teamed up when Lambert was a contestant on American Idol in 2009. And this will be Queen's first North American tour since 2006 when they went out with Paul Rodgers.
