Radiant2007 :-):  Yes. we had a grand old time last night, shared some memories, and favorites with one another.  I wish you could have stayed up all night, but it is all well chronicled here for your enjoyment today.

Bill Monroe is considered the father of Bluegrass music.  His home state was Kentucky, and Kentucky is where the blue grass grows.  Blue grass is actually not native to North America.  It was brought here from Europe, where it grows prolifically all over.  Why it is called blue grass, I don't know, and I can't really find a reason.  But, it is a deep green grass, and maybe in some circumstances that green can seem blue to the eye.

Zydeco has it's roots in Cajun music, which developed predominately in Louisiana.  But, it's Cajun music with a twist, there is bluegrass, jazz, blues and rock influences in it.  Yes, it is played mostly in the southern U.S., but since communication has gotten so much better, it is enjoyed by millions all over the world.  Anyone care to waltz?  Yes, it is often in 3/4 time.

Woody Guthrie was a song writer from the U.S.A.  His music is pretty grass roots folk.  It doesn't belong to Bluegrass at all.  His son, Arlo Guthrie, has also enjoyed some fame as a singer/songwriter in this country, with the songs "Alice's Restaurant Massacree", and "The Motorcycle Song".  He's uproariously funny, and if you haven't heard any of his music, you should make an effort to find it.  Maybe on Pandora, I don't know.
