I don't really know if any of these are from the late 50's. I'm pretty positive several of them are from the sixties. But whatever, it's a great listen. There's a weirdo version of the Addam's Family theme with a bizzaro jazz section that seems completely exempt from all of the TV broadcasts. There's great stuff on there though.
And Fugazifan, like your signature. That could very well be my favorite Stereolab song.
