In late 1976 I bought the RCA LP record, Space: 1999. While I was a little disappointed in the incompleteness of the album, and the seemingly interminable space-outs between the cuts, it contained music from the series ― its first season, as that was "1999" at that point.
In early 2022, with a degree of nostalgia, I welcomed a Silva Screen Records CD set: Space: 1999 - Year 1 & 2
Barry Gray wrote material, very much in the Gray style, for Year One; Derek Wadsworth jazzed Year Two to great effect.
Both sides work in that they match, respectively, Space: 1999's seasonal timbres....
Year One: winter
Year Two: summer
