"Meow" is the sound one is often recorded to make when Grave Dancing. There is most certainly proof of this in the Documenthairy on BBC1 called "
Mewt Meow: The Noise of Liberty" and on Channel 4 called "Meow: Dancing on Graves (Feck)". ITV missèd out, har har! Yeah Channel 5 did it, whatever. They can go predict a sexual stylus invasion or something.
