The series includes music and sound effects from Thunderbirds and Anderson's other series: Stingray, Captain Scarlet and the Mysterons, Joe 90, UFO, and Space: 1999.
I was going to ask which tracks are from which Gerry Anderson series but to me this score sounds distinctly Japanese to me.
While I was aware of the British Thunderbirds series I hadn't seen it until a few years ago. This series aired on Showtime in the 80's and I loved it at the time. Its a nostalgia thing for me.
So is Wiki incorrect about the music or perhaps the UK airing used Barry Gray's music while the US version used the Japanese soundtrack?
