The Duke answered this question years ago. I don't know why people insist on making Jazz some kind of fly by night music that goes in and out of style like some teenage top forty 'hit'.
The 'good stuff' goes through life with you. There is no new and old. Just the good and the other kind.
Today I was watching a thing on youtube about 'million dollar' stereo systems. The most beautiful rig I have ever seen. Had three 10" RTR decks. Power amps the size of dog houses. You get the picture. One of the tunes he played on the RTR was "house of the rising sun". Didn't catch the female singing. Couldn't hold a candle to Dee Dee, but there it was.
Now read the wiki article. Note the dates, times and places concerning the 'origin' of House of the rising sun. Without doubt, it goes in the 'good stuff' column. Humans will be playing it forever.
Only the 'other kind' is blown away by time.
