YES YES YES!!! THAT'S IT!!!
You have just solved a 35 year mystery!! Thank you so much!! 😃
Also that explains why I couldn't find it - it didn't chart here at all. Looks like it was released in 1983, so 1984 would be about the time I saw it on TV.
Thank you again! 😃
Edit; I'm surprised NZ On Screen would know about it - the guy was a French composer! :)
