He was the king of Queen and his crown could be yours — for the right price. Freddie Mercury’s extensive collection of costumes, fine art, and even handwritten working lyrics for “We Are the Champions” and “Killer Queen” will be auctioned in September. Queen’s frontman had said he wanted to live a Victorian life surrounded by “exquisite clutter,” and he left it all to his close friend, Mary Austin, when he died, at 45, of AIDS-related pneumonia in 1991. Austin, who has kept most of it the way Mercury left it in his home in the upscale Kensington neighborhood of London, said she had reached the “difficult decision” that it was time to sell it all, Sotheby’s said. Hand-written lyrics for the band’s famed "Bohemian Rhapsody" show that Mercury toyed with calling the song "Mongolian Rhapsody."
