LOL !!

I once heard - on Radio 3 of all places, back in the old days - a Dixieland trad jazz band playing something that the announcer said had been influenced by traditional Celtic (think that's the word he used) sources. And damn me, it WAS too. Fascinating sound, minor key, started slow and then wound it up. I can't remember much more about it except that it really, really worked. And they were a straight New Orleans trad outfit, not a "fusion" band.
