At Queen's press conference on Thursday at Madison Square Garden - to announce their North American tour with Adam Lambert - guitarist Brian May hinted this could be their swan song.

He went on to say, "Having this opportunity is great for me.  We're still healthy enough to go out there and tread those boards one more time."

The tour kicks off June 19th in Chicago and the band will appear at the American Airlines Center in Dallas on July 10th. 

Here's Queen's rock anthem "Fat Bottomed Girls" from iHeartRadio.  This concert clip features Paul Rodgers on lead vocals.
