Well well, a subject near to my heart. I work for that there company that designs theme parks, and I love real folk music AND recreated real folk music. And the answer is: it's pretty much pure luck regarding "authenticity", although any theme park music is going to be cleaned up and sweetened at least somewhat. The people in charge of Entertainment often find live entertainers who are truly superb, simply because what they are offerring is a perfect fit for the musician(s). My friends who used to be the "Big Thunder Mountain Boys" at Disneyland had it made- getting paid to practice all day long! Consequently, they are now some of the finest acoustic musicians around Southern California. And the stuff they played in the park was REAL Bluegrass, regardless of what the "purists" think. They, by the way, are the guys who recorded the BGM for Frontierland, which is why it is so terrific. Sean M. is right- that stuff is great, and the stuff played on the SS Columbia could have been more "authentic", but....it's just the luck of the draw. It's wonderful that those in charge actually make the effort sometimes to bring REAL music into the theme park setting! Last year I was at EPCOT in Florida, and there was a group of Rumanian Gypsies playing in one of the lagoon alcoves- they were stunning! I stood there for at least an hour, enjoying what was about the most genuine Gypsy music I've ever come across in the US. So sometimes it's dead on, and sometimes it's Norman Luboff. BTW, CarolC- your friend troll has one of the greatest gigs in the world. I would so dearly love to go back a few years and do what he is doing. Tokyo Disneyland is great, Tokyo DisneySea is stupendous, living in Japan is wonderful (the people, the traditions, the culture), AND he gets paid to practice every day!!!!
