I can faintly remember this song I think, It starts :- You've got to have skin, miles and miles and miles of skin. It then goes onto gorey detail about it holding things like your guts in. That is all I can remember of that one at the moment, but I remember another along the same lines that goes :-You need skin, take good care of it, don't harm a hair of it, 'cos you need skin.
Keep it clean, soapy water every day wash the dirt and smells away, 'cos you need skin.
