Hello Markus,Yes, Kentucky is the "Bluegrass State" and the home of Bill Monroe and probably Blue Grass Music. If you need lyrics, you can't find a better place than the Digital Tradition Folksong Database. Also, you can search this Mudcat Cafe forum for discussions about the songs or bands you are interested in. I found this link to some Blue Grass songs recently in a discussion at this place.

I guess you know that the reason for bluegrass and racehorses here in Kentucky is the limestone rocks. They say that's also the reason for good Bourbon and the paint industry which developed around Louisville in central Kentucky. There is a saying that we are the "Land of fast horses and beautiful women." Locally we say the "Land of beautiful horses and fast women." ;-) If that doesn't translate into German very well, get some help on the translation.
