Set for bohemian rhapsody

Adam Lambert at the 2016 Barcelona concert.

Since 2011, Lambert, the American Idol season-eight star, has been touring with Queen.

The band also features Roger Taylor on percussion, Spike Edney on keyboards and Neil Fairclough on bass. Their successful partnership has seen over 70 sold-out shows worldwide with over a million in attendance.

Speaking of the upcoming shows, Lambert says: "I have been lucky to visit Asia recently, and am so thrilled to be able to return to perform with Queen. We are going to give you a show to remember."

Recalling Lambert's first performance, May says the first gig they did with him was for about 400,000 people in Eastern Europe. Then, May says, Lambert just walked out and smiled and did his part, which was great, adding: "He also has humility and he goes out there and he says: 'Look, I'm not Freddy Mercury (Queen frontman who died in 1991 of bronchopneumonia brought on by AIDS), but this is what I do and this is what I would like to do with you guys, and let's celebrate.' And people immediately feel that he's genuine, because he is."

May, who grew up in Hampton, in London, met the members of Queen in 1970 when they were all university students, including then art student Mercury, biology student Roger Taylor and John Deacon, who was studying electronics.
