In all honesty, as fantastic as these pilot episodes were, it doesn't surprise me at all that this show wasn't picked up. The demographic that would appreciate it was vanishingly small by 1982. To someone not into jazz, it probably looked like Lawrence Welk. Buddy ordinarily had a charismatic stage presence, but in this he looked unprepared for the mic. The choice of guests didn't help - Woody Herman in particular by then was a poor choice... Buddy and his fans might appreciate his presence, but not the general public. The staging was also a bit weak - Mulligan was relegated to being Mel Torme's accompanist, so he just looked like some old guy. And if I weren't into jazz, I'd think the Stan Getz pairing rambled on forever. The show desperately needed some younger guests, like Chick Corea, Freddie Hubbard, Mike Stern, etc. As it was, to a network exec it probably looked like a bunch of old white guys reliving their bygone years. An incredible piece of history, but also a missed opportunity.
BTW, Lin Biviano on lead trumpet, I think. And did Buddy ever mention Steve Marcus' name? His band's best soloist for many years, he was an incredible player deserving of wider renown.
