Duets by late pop legends Michael Jackson and Freddie Mercury are to be released 30 years after they were recorded.
The King of Pop laid down the tracks with the Queen singer at his home studio in Encino, California in 1983.
Now Queen guitarist Brian May is working with longtime bandmate Roger Taylor and producer William Orbit to finish the tracks for release later this year, the Hollywood Reporter revealed.
"There are a few items in progress. We will have something for folks to hear in a couple of months' time, hopefully," May wrote on his blog.
The rocker was given access to the recordings by the Jackson estate in 2011 and has been working on the tracks for the last two years with Taylor and Orbit. They have reportedly added new guitar solos and vocal harmonies.
Mercury and Jackson reportedly had a falling out shortly after the 1983 recording session in Encino.
According to Jim "Miami" Beach, Queen's manager, the disagreement stemmed from animal-lover Jackson bringing a llama into the studio. "Mercury rang me and said: 'Miami, dear, can you get over here? You've got to get me out of here; I'm recording with a llama'," he told NME.
A source from the Jackson estate told the Daily Mail the falling out was simply caused by the pair's difficulty in arranging any additional recording sessions.
Mercury died in 1991, while Jackson died in 2009.
