We are considering Black Cat, as we all own black cats. Black cat ceilidh band seems to sound better than barn dance, which is why I wondered if people would not know what it was, or would expect would Scottish or Irish music.
I'm a bit wary of things they can mis-spell like Ave a Go (though I like it) or Hoe Down. I'm in Thompson's directory as Mo Barn Dance Parties and I get some very dubious voices on the phone, and lots asking if I do childrens parties. I say, 'only for over 7s' which is usually the end of that, though I was persuaded to do a fancy-dress dance for a 4 year-old on a Peter Pan theme and it went really well.
