‘There Must Be More To Life Than This’ the collaboration between two of music’s greats Freddie Mercury and Michael Jackson was left unfinished because of the chimp!

It was almost 30 years ago, when Queen legend Freddie Mercury reportedly stormed out of the recording studio, when Michael Jackson brought along Bubbles to the recording sessions.

Mercury couldn’t handle The King of Pop’s weird attachment to his chimp friend, according to the Daily Mail UK, so the song was never completed.

“‘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. “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.”

‘There Must Be More To Life Than This’ is contained on Queen Forever out this week. Hit play to watch the trailer.
