A mythical young man of rather dubious character.

We'd like to have you all join in with us on this one, and help us find the groove, by patting your feet, or popping your fingers, or clapping your hands, or shaking your heads, or shaking whatever else you want to shake... while we do a little thing we call "Filthy McNasty".
