I was adjudicating a bunch of social and demo dance groups a few years
ago. One of the most effective groups (led by local teacher Claudette
Sigg) did 2 cpl dance in two sets that were side by side so that the
audience was at the head of two very short sets, rather than beside one
longwise 4 cpl set.. They did The Happy Meeting and Sandy o'er the Lea
and some compact 2 cpl reel that escapes me now (maybe The Clansman).
The arrangement made very good use of the rectangular stage and avoided
the problem of having dancers with their backs to the audience --
particularly nice since most other groups were arranged lengthwise on
the stage with the men having their backs to the audience which gave a
less than desirable image to the audience when the gentlemen bowed to
their partners at the start of the dance!
It all struck me as much more effective than to be demonstrating dances
that can only make the audience say "Wow! I could never do that!" At
least in our area, we seem to have an abundance of spectacular
performing dance groups and a dearth of demonstration groups that aim to
recruit new dancers. Not that I do either one, so I'll shut up and
crawl back in my hole.
