I'd leave the swords for the rapper and Highland dancers to attack each other with.

Morris dancers are quite enough with sticks and other blunt instuments( north west morris), beer, or very blunt instruments (ballistic accordians). besides, they spend a fair amount of time attacking the ground, which would not be at all good for your fancy swords.

Or for the ultimatly dangerous weapon you have to go to the BroadWomen sword dance. Instead of 4 swords laid to form a cross to dance round, broardswords, we use 4 of our ladies are laid to make a cross.... um four of our ladies are crossed

I give up. The ladies are not crossed. We wouldn't dare do that. They're certainly not laid on stage. We don't do that kind of dancing. This is broadswords, and now replace the women with men, and the swords with women. You get the idea...
