A collection of Freddie Mercury's prized personal possessions is going up for auction. The Queen singer's London home has remained untouched since he died in 1991, and now its contents are going up for sale by Sotheby's auction house. The contents include Mercury's stage costumes, the jeweled crown he wore on stage, objects he collected on his travels and his hand-written lyrics to "We Are the Champions." The roughly 15-hundred items in the Freddie Mercury collection will first be exhibited at shows in London, New York, Los Angeles and Hong Kong. The auctions will begin in September.
