I was a bit surprised when I did a search that I did not find a mention of the "Retro Cocktail hour" internet broadcast. The shows are actually 2 hours. The music is what you would hear in a lounge during the late 50's and 60's. There is a lot of Exotica and Les Baxter music.
Of all places, it comes from the University of Kansas, but its a good program and you can listen to any of the last 10 shows. The link is:
