I think Dick The Box nailed it when he recommended putting on a show and interacting with the audience. I saw a local dance team perform in a country pub last year. The bar was filled with young lads drinking lager and there were plenty of sarcastic grins and sneers when things kicked off. It looked doomed, but the team's captain kept circling round the pub chatting and joking with everyone, and pretty soon the dances were getting jovial applause. By the end of the evening the lager-drinking lads were all joining in the dances and having a roaring time. Fun is infectious, and the morris should be fun, yes?
