Kath, whereabouts in SDAK? Have you checked with any of the state arts councils? You might be able to find one in Wyoming or Nebraska, esp. Wyo, if they didn't have to go clear over to the eastern part of SDak.You might check with Challenge Music, here in Casper. They have a website, I think it is just their name with .com afterwards. He seems to know a lot of people in the music community. Hell, Chris LeDeux is just up the road from here, who knows....:-) Last I knew he was still in the phone book. While it's not dance music, per se, the ole' professor Peter Schickle is up there, too, ya know.... "Switched on Bach"?!
Hope this helps. Let me know if you need more done in Wyo and I'll see what I can do.
