The answer can be found on Led Zep IV:
Hybrid mama said the way you move
gonna make you sweat, gonna make you groove
Oh, oh, child, way you shake that thing
Gonna make you Burnt, city make you sting.
LOL. I went to the first Led Zepplin concert ever in the Filmore-West in SF...many 'moons' ago. That's still the best concert I ever attended.
