Brian May has said that more previously unreleased Freddie Mercury material has been found.

Queen drummer Roger Taylor recently confirmed that Brian May is finishing work on a number of tracks Freddie Mercury and Michael Jackson duetted on, but now, May has said that even more Mercury material has been discovered. Speaking to Mojo magazine, via The Guardian, May commented: "There's more in there than we thought, in the Queen source archive. I'm a little nervous of saying there's an album there, but there's certainly a few tracks... We've found some Freddie vocals, some demos."

Earlier this year it was reported that around three tracks Mercury and Jackson recorded in 1983 will be made available to fans. Speaking in July, May said there would be "something for folks to hear" in two months' time.

However, though the songs have not yet emerged, Taylor went on to tell Classic Rock Magazine that the songs are being worked on at the moment, primarily by May. "Brian especially has been active working on old tracks. A couple of tracks that Freddie did with Michael Jackson," he said. Adding: "They've been hanging around for years and years and Michael's estate haven't really been able to make their mind up about what to do with them. So we suggested we finish them and see. They're pretty good – one of them is great."

Roger Taylor recently let slip the band want actor Ben Whishaw to take on the role vacated by Sacha Baron Cohen in the forthcoming Freddie Mercury biopic. Sacha Baron Cohen had been set to star as Mercury since the film was announced in September 2010 but this summer he pulled out of the project, reportedly because he and Queen, who have script and director approval, were unable to agree on the type of movie they wanted to make.
