Some points arising from your interesting post, Bev:
NHOP emerged as very articulate - and I don't just mean on bass - fluent in English with an engaging Scandinavian/American voice. Little touches of ego made it more meaningful than the sort of interview where everyone the subject has played with is "wonderful". He said he loved duos as he got more of a say and his Looking at Bird with Archie Shepp is a favourite of mine.
Jazz has always been the poor relation at the BBC, moved from waveband to waveband as upper class bosses never quite knew what to do with something they had no personal liking for. Nearest to a big man as its protector was Humphrey Lyttelton, Eton educated, but digging trumpet rather than than hunting.
To its eternal damnation, the BBC with its UK monopoly played less of a part in my jazz education than the more-or-less-"pirate" station, Radio Luxembourg. There in 1959 on a show called "Jamboree Jazz Time" I first heard Coltrane and Ornette Coleman. Again in those years, Willis Conover's "Voice of America Jazz Hour", heard through a barrage of static brought me the sounds which were nowhere to be heard on the BBC.
