I don't know how much jazz was in the air in the USA in the 1960s and 70s, but over here it was just a few hours during the week, so missing them always hurt, and listening always was full of surprises and had a magical quality that the ubiquitous availablity of internet files does not have - at least for me. I do listen to foreign stations on the internet radio offered by our TV server, but the musical level is not as high as during the years when real people were selecting the records in realtime. The times they are a-changin', I suppose. Even local classical programs sound to me like they have a few hundred albums on hard discs they keep repeating and rarely add something new.
