A series of never-before-heard duets between Michael Jackson and Freddie Mercury will be released this fall.  Britain's "Sunday Times" says Mercury's surviving Queen bandmates Brian May and Roger Taylor have been preparing the tracks for release, though it's still not clear how they will surface whether in the form of an album or otherwise. The songs were originally recorded in 1983 but were never fully completed over a reported dispute between Jackson and Mercury.  A manager for the late Queen frontman tells the "Times," while the two got on well there was a time when Freddie called him up to complain that Michael had brought a llama to the recording studio.  It was then that Mercury apparently said he had had enough and wanted to get out. 

Mercury died in 1991 at the age of 45.  Jackson died in 2009 at the age of 50.
