[Callers] describing contra to other dancers

I have the opportunity to be interviewed about contra dance on a weekly radio program on a public radio station in our community. This program serves local country and western, salsa, swing, tango etc dancers as well as doing some promotion of folk, Scottish etc. The format is usually to play representative music by well known groups, have a few live local musicians play, interview someone knowledgeable, then announce where the dance events are happening that week around the state. I will have 15-20 minutes to talk, probably interspersed with tunes.   I see this challenge as somewhat different from our contra-community-wide problem of describing contra to the general public....the audience here is a group of folks who already do other sorts of dance. I would welcome sound bytes from anyone with this in mind. What points would you folks make?
