[Callers] Interesting dances without role-specific calls?

Hi folks, I’m introducing a dance series to larks/ravens next weekend, and to ease everyone into it (/in case of emergency), I want some dances handy that are non-trivial and interesting (so, not glossary dances, but one an intermediate-to-advanced crowd would enjoy) WITHOUT role-specific calls—i.e. nothing where you tell the gents to X or the ladies to Y. What are your favorites?! Cheers, Maia
