Sweet put out some great tunes, in my opinion, back in the 70s, including 'Ballroom Blitz', 'Fox On The Run' and of course 'Love Is Like Oxygen.'

The band, from England, came about in the late 60s and became popular in the 70s as a glam rock act.
They scored big in the UK with thirteen top 20 hits.

The four member group, Andy Scott, Steve Priest, Brian Connolly and Mick Tucker became a three member group in 1979 when Connolly left to pursue a solo career.
The band ended up disbanding in 1981.

Two surviving members of the band, Andy Scott and Steve Priest continue with their own versions of the band....Scott in the UK and Priest in the US.
Of the original four members, Brian Connolly died in 1997 and Mick Tucker died in 2002.

Since the mid-1980s, Scott, Connolly and Priest have each played with their own versions of Sweet during different periods of time. Connolly died in 1997, and Tucker died in 2002.
The two surviving members are still active in their respective versions of the band: Scott's is based in the United Kingdom and Priest's in the United States.

The song 'Love Is Like Oxygen' was a bit of a different direction from their other recordings, featuring high vocal harmonies and it was a more guitar driven tune than most of their other songs.

The tune reached the number 8 position on the US charts.
Here's a great version of the song.
