Hehe... living IN cajun country, I know who Dr. John, "bou ray and the zydeco twister" and "Boujoulai" are. I'd be pretty surprised if many others have heard of 'em here though...
More probably have heard of the "Mardi Gras Mambo"...
Good tunes, though I'm not a big zydeco freak

...
Traditional cajun music is pretty cool though... happy sounding music with some pretty warped lyrics... if you can translate the Cajun French in it...
