Queen's Freddie Mercury decided against recording the duet "There Must Be More To Life Than This" with Michael Jackson after the King of Pop brought along his pet chimp Bubbles to the recording studio.

"I'm not performing with a f-king chimp sitting next to me each night," said Freddie, according to David Wigg, who dishes in an upcoming book.

Wigg, in an adds, "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 several sessions of dealing with the chimp and Jacko, Freddie became fed up and the cut was left unfinished.

A rescued version of "There Must Be More Than This" is featured on Queen's two-CD set, Queen Forever, in stores now.
