Ceilidh/Ceili? Barn Dance? Contra Dance? Social Dance? Folk Dance? Square Dance?

A roomful of people having fun dancing to great music, executing the patterns that the caller calls from the stage. No footwork, no need to remember anything - just pure fun!
Whatever your needs, John & Karen Sweeney can make your event a success and ensure that everyone has a great time.
