[Callers] Teaching 'contra' to adults with various developmental disabilities

I've been asked if I will teach/lead a one hour long 'contra dance' at a day program for young adults with a variety of physical and cognitive disabilities. (The staff probably would be happy for me to do more than one session, but I'm not willing to commit to that. At Least not now.) My usual repertoire for a wedding or party of non-dancers seems tricky for many of the clients--especially those who are uncomfortable being touched. I did a similar event about 10 years ago--at a different program-- and it didn't seem many of them had a good time. I'd like to figure out a way to make it fun for this group. I have a couple of ideas and am looking for more. Have you ever led a dance/music event with a similar population? I'd appreciate any advice/suggestions. Bree Kalb Carrboro NC
