Lots of great suggestions. It seems that Barry Finn and I think along similar lines, which worries me a great deal. "Bloodlust, gore, murder & mayhem": absolutely! We could make it a body count workshop, with a black board or a flip chart to keep score.

Songs in languages other than English have been well received in the last couple of years.

My personal favourite topic (for professional reasons, I suppose) is crime and punishment.

How about a workshop on songs based on historical events. Of course, that would cut across other boundaries (crime, war, rebellion, disaster, etc)
