I was such a fan of the show and the music that I actually called Frontiere in Beverly Hills back when I was in college in Florida (mid 70s) and spoke with him. Besides praising his music, I asked if he had any plans to release a recording. He said no, and that he had donated all the TOL tapes to his alma mater, which, if I remember correctly, was like the University of Wyoming. (Can anybody confirm this?) He didn't think there'd be a demand for it.
I was happy hear about and pick up that GNP release many years later, but I wondered if anyone else contacted the school or found out if there were any other plans to release more of the music.
Also, when I talked to Frontiere, he had recently worked with Dan Fogelberg preparing the orchestrations for his album "Netherlands." If you're not familiar with it, pick it up, it's really quite a great album and Frontiere's work on it is really inspiring. Dan Fogelberg died just last month of prostrate cancer.
