Aloha!
I'm 90 percent certain I listened to this concert LIVE via FM Tap on my cable system in 1987. That was before streaming (obviously), when Cable TV systems still did FM Taps where they pumped in about 30 FM Stations via microwave links from all over the country into your FM dial. I can't remember if KJAZ, or WBGO or KCSM broadcast this live via satellite, but SOME Jazz station did. I'm also pretty sure I recorded it on Cassette. I just have to find it.
Anyway, it was a kick finding it on Youtube. Brought back a lot of memories;
