in leonard feather´s own book: "the jazz years, earwitness to an era" (new york, 1987) is on page 302 under honours and awards this entry: "1971 nominated for emmy award for producing "the jazz show", a series seen on knbc, los angeles".
so is "knbc" another broadcasting company than "nbc"?
nothing more in his book about this tv-show. (i did only a quick look but found nothing, sorry)
keep boppin´
