Emily,

This is the point where censorship belongs. Where it is the personal choice of the performer. You are also correct about the alterability of folksongs. This is called arranging. :-) <--- note the grin and the obvious humor to follow. If your prefered arrangement is a gutless Arthur Mc Bride, totally lacking balls and power, thats your right. :-) still grinning and poking fun.

As far as authenticity goes. If its as authentic as any folk song can be, say so. If its your take on a tune, say so. Simple as that.

Do it your way. Stick up for your principles, you'll always get my vote if not my ear.
