The BBC WAS pretty high quality broadcasting, even if there wasn't a lot of jazz. There were some riveting interviews - two that really glued me to the radio were long ones (and hour with virtually NO music, as I recollect): Sun Ra and Francis Wolff (not together )
Generally, except for "Jazz record requests", which I never usually bothered with, there was quite a bit of discussion which, even though I knew that eg Humphrey Lyttleton had his prejudices, was often interesting because, despite the prejudices, I knew that Humph could hear stuff a lot better than me. (And Humph LURVED long, slow, greasy blues! Whether they were by Coleman Hawkins or Jimmy McGriff.)
Things have changed and I don't listen to the radio now, but in my view, quality definitely wins.
