Mercury-Jackson duet blown by Bubbles

Why did that Michael Jackson - Freddie Mercury duet never get finished?

Mercury didn't want to be produced by a chimp:

They were supposed to cut “There Must Be More To Life Than This,” but Mercury couldn’t handle The King of Pop’s weird attachment to his primate pal, The Daily Mail reported on Sunday.

“‘I’m not performing with a f–king chimp sitting next to me each night,’” Mercury exploded, veteran show business journalist David Wigg will write in a book, The Mail reported.

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.”

Got to be honest, it sounds a bit like Bubbles was a yes-chimp.

By the time Mercury turned up to work with Jackson, it was pretty clear that Michael wasn't like other boys, so I suppose it's more surprising that Mercury agreed to the recording session at all.

On the other hand, if he lasted for a "few days" of Bubbles overseeing the desk, there's two questions:

One: Did Mercury keep thinking 'well, maybe he's just taking time to find his monkey feet and might start being a useful member of the team' for those few days?

Two: A few days? How long did it take to knock out a crummy duet single?
