In Donny's defense ... he has a loyal following of ballroom dancers who love to mix it up with new and old tunes. I'm sure someone made up a linedance to that dreadful NaNa song, and the crowd probably eats it up. It's no worse than the Electric Slide or the Cupid Shuffle, right? I just would never see an opportunity to introduce it to my clientele. Donny's crowd is different - they do whatever he tells them to do, and he gets right up on the floor WITH them - that's something I NEVER do!
