Bert, that is the caller's dilema.
The English country dance clubs (EFDSS - dancing Playford type dances) run the risk, nowadys, of being driven by the novelty seekers.
The people who call are the ones who go to Saturday dances / courses / festivals / and buy books. So they want to try out all the new dances, using the members as guinea pigs.
Beginners are very happy when a dance crops up that they recognise.
And in between are the majority of club members who can dance better when they know a dance well enough and can think about fitting it to the music and reacting to the other dancers rather than what happens next. They DON'T want to dance the same dance till they are sick of it, but are quite glad when I call a chestnut ... "we used to do that a lot, haven't done it for ages"

I rarely go to English Ceilidhs now, haven't the energy for the clubs, find the one off fund raisers boring to dance at.
Calling them is a different story, I never get bored with seeiong people enjoying themselves, whether I need to call simple dances, that end up across the music, the latest complicated composition, or anything in between. I enjoy the challenge of fitting the programme to the dancers.
