I've been trying to work out Sasai's involvement in anime as per his interview and VGMO profile.

Mysterious City of Gold (1982)
Music credited to:
Shuki Levy, Haim Saban, Ryuji Sasai

Windaria (1986)
As far as I can tell this seems to have been primarily scored by Satoshi Kadokura. I watched the ending credits but didn't see Sasai's name (could have missed it). I suspect this album is not the complete score. According to his VGMO profile Sasai seems to have had pretty in-depth involvement.
Adventures of the Little Koala (1984)
Can't find any Japanese episodes. The NA dub had remade music, as was typical of a lot of early dubbed anime.
Then there's his post-Square work, done under a pseudonym. Maybe when he stops doing live shows he'll settle in and release some of his older work.
