Tracks featuring late legends Freddie Mercury and Michael Jackson could be released next year (12), according to rocker Brian May.
The Thriller hitmaker worked with Mercury in the 1980s on a number of secret songs, which May first revealed existed following Jackson's death in 2009.
The Queen rocker said, "(Jackson) used to come and see us when we were on tour in the States. He and Freddie became close friends, close enough to record a couple of tracks together at Michael's house, tracks which have never seen the light of day."
Two of the songs were later leaked onto, but May has revealed they could be nearing an official release.
He tells London's Evening Standard newspaper, "(They'll be ready) in the next year. We've been talking to Jackson's estate and they're happy."
