Two 80's legends came together to create a powerful pop ballad about 33 years ago, but surprisingly, the song was never released -- until now.

'There Must Be More to Life Than This,' a song by Queen's Freddie Mercury and Michael Jackson, was written by Mercury for his album, 'Hot Space,' in 1981.

Reportedly, the Queen's frontman recorded Jackson's addition to the song while touring in Los Angeles. However, the finished version didn't feature the King of Pop's vocals when Mercury released the song in 1985.

British producer William Orbit, who's worked with artists like Madonna, remixed the catchy tune and put M.J.'s vocals back on. The song will appear on Queen's double-disc album, 'Queen Forever,' arriving Nov. 11.
