Music CD for TV-series "Il était une fois... l'espace"

I'm looking for the music CD for the French 1980's TV-series "Il était une fois... l'espace" or "Once upon a time... Space", as its English name is.

The CD is apparently a double CD, with 30 tracks on each CD. (Search for it at French Amazon, amazon.fr, and you'll find the CD I'm talking about. Unfortunately, it seems to be out of stock.)

The CD doesn't have to be new, but must be in very good condition.
