[Callers] First Dance - Adult ONS

Hi, I'm starting a new Community Dance series in our area with no recent history of any trad dance. It will likely be nearly all beginners and geared toward adults/teens. Thanks to this List I have a good collection of ONS dances to choose from, but I'm having trouble deciding on the First Dance. I'm thinking a non-partner dance that folks can be encouraged to join as they arrive (before they sit down) with very little or no teaching. I've considered Circles/F&Bs with variety of who goes in, probably with claps. Or CL, F&B 2x, CR, start a promenade wave at a random spot, people coupling up one after another till all are promenading (I'll be on the floor with them). I'm concerned with the usual -- looking easy enough, looking interesting, not embarrassing, getting them involved before they have a chance to think much about it. I have no idea how many dancers I'll have. Any suggestions or recommendations would be much appreciated. Thanks, Sue Sue Robishaw, U.P. of Michigan
