London, July 29: Freddie Mercury and Michael Jackson recorded three songs during a 6-hour-session at the King of Pop's home studio in California in the early 80s.
However, the tracks were shelved after the superstars fell out over when to schedule a follow-up session, but Queen band member Brian May has taken permission from the Jackson estate to revive the duets, the Daily Express reported.
May said that working on the tracks has proved to be 'exciting, challenging, emotionally taxing but cool.'
The trend has shown tracks released after star's death have gone on to become big hits, four years after Mercury's died in 1991, his band Queen released his final recordings and out-takes.
The album entered the charts at No 1, went quadruple platinum in the UK and sold about 20 million copies worldwide.
Michael Jackson has earned 800 million pounds posthumously. In the year following his death, the superstar sold 24 million albums plus an additional million records by the Jackson 5 and The Jacksons which brought in 250 million dollars.
Publishing rights have helped earned 88 million pounds and TV and DVD projects have helped bag 256 million pounds in the kitty. (ANI)
