Of course, no really good music has come out since the war -- World War Two, that is. With the exception of Gloria Estefan and a few keen dance pieces of the 1990s, the world of music has been nothing but a vast wasteland.
Before the war, there was a kind of dance music called "swing" that bred a style of dancing called "the jitterbug" danced by people who spoke a language known as "jive." Jive contained words like "cat," "licks," "on the cob" (as in corny) and the really great word "icky" which referred to sentimental music -- the kind that was preferred by the parents of jitterbuggers.
If you ever wanted to learn this obscure language, you can get a good start listening to this very rare circa-1933 excerpt of a radio program called "Inside Story" that attempted, in this episode, to help its audience understand just what their children were saying and doing.
So, all you hep cats and gators get ready to learn some jive!
