So I'm doing recon to find Maurice Jarre's entry to the above series (not buying it either, and I'm up to 1978....), but found this curio to share with every one- one person in particular, hope you see this J, I'm sure you'll get a kick out of it.
I passed another one I forgot to nab that Legrand scored as well. Charles Bernstein & Randy Edelman also popped up during various searches. Brad Fiedel on Seven Wishes of a Rich Kid from 1979 season 7, ep.7. & A Movie Star's Daughter from 79 season 8, ep.2 John Morris on season 7 ep.5 Make Believe Marriage. I haven't watched the Legrand yet.... nor has anyone else with 20 odd views. Eventually.
Edit: I found it!! Jarre scored One of a Kind in 1978 for Harry Winer, starring Diane Baker season 7 episode 1. https://m.imdb.com/title/tt0253406/?ref_=m_ttep_ep_ep1 Bollocks...search is fruitless except some genius posted a commercial break from my episode, allowing me to hear one tantalizing bar.
I went through the episodes again to see if I could find more on Youtube that were missing the composer credit on IMDb. I found half a dozen more, including an Anton Sanko; one of his earliest scores.
