Freddie Mercury backed out of Michael Jackson duet over chimp

Queen singer Freddie Mercury reportedly stormed out of recording studio nearly 30 years ago, after Michael Jackson brought along his pet chimp, Bubbles.

Mercury and the King of Pop were supposed to cut 'There Must Be More To Life Than This', but the former couldn't handle Jackson's weird attachment to his primate friend, reported New York Post.

"I am not performing with a chimp sitting next to me each night'," Mercury said according to veteran show business journalist David Wigg's new book.

Wigg went on to write, "Freddie got very angry because Michael made Bubbles sit between them and would turn to the chimp between takes and ask, 'Don't you think that was lovely?' or, 'Do you think we should do that again?'

"After a few days of this, Freddie just exploded. He phoned his manager and told him to 'get me out of this zoo.' Freddie then flew back to London, leaving the track musically unfinished."
