Recorded for the soundtrack of the 1986 West End musical Time, this stripped-back version of the song - full title 'Time Waits For No One' - is only just seeing the light of day this week, after a decade long search for the song.

The version that was previously released featured the Queen star accompanied by dozens of layers of backing vocals, while this version features a different vocal take, and only a piano as accompaniment.

The video below shows the Queen frontman – who died in 1991 – singing at the Dominion Theatre.

'Time Waits For No One' was aired on BBC Radio 2 last night.

The song was originally written by Dave Clark, who's a member of 1960s pop group the Dave Clark Five. He told listeners on the BBC that he felt that the demo had a quality that was missing from the finished version.

"When we first recorded it, I went to Abbey Road and we ran through with just Freddie and piano. It gave me goosebumps. It was magic," Clark told Radio 2's Zoe Ball.

"Then we got down to recording the track and we [added] 48 tracks of voices, which had never been done in Abbey Road before, then the whole backing.

"It was fabulous - but I still felt there was something about the original rehearsal."

Clark also explained that he found the demo recording in 2017. He said that he then isolated Mercury's voice, as well as bringing in the original keyboardist Mike Moran to record a new piano track.
