Oh! That was the Swing Dance Camp at Palm Springs this past summer. I was there, and it wasn't just swing, there was hustle, Argentine Tango, NC2step, CW, and of course West Coast Swing. The Jack and Jills were great - as you noticed - but there was General Dancing from 8 until 4 a.m. Contact People Who Dance - "Jay" he'll be able to tell you all the music including this tune. I'm going again this summer too - it was the best $125 for 3 days I ever spent!
