AABB, or AB?

Hullo All, I'm curious what others do in the case of 16 bar dances. If one has a dance like the Canadian Barn Dance, the similar La Chapelloise/Cdn Gay Gordons, or Nottingham Swing, and so on, that repeat after 16 bars of music do you: Ask the musicians to play a tune AB or Generally allow or expect a two part/32 bar AABB tune and (try to) keep track of when one is in the B zone, ask for once more and expect two more repetitions of the dance? (or plan _further_ ahead, four dance repetitions out, for twice more the music.) Do you feel there a best practise? Does it depend on whether you regularly work with a band/group of musos? How confident they are, if _they_ can track that. Should it all be on the caller? Or do you simply avoid this situation? I have some 3 to 5 dances of this nature I regularly have handy and have been taking it all on myself. I have several bands I regularly work with where I might choose these dances and it was suggested by one group recently they might provide AB/16 bars. This would actually be a tracking relief for me and I think provide a more (logical?) musical framework for the dancing of it. Thanks, John -- J.D.
