if you go swimming at a lake out in the sticks of bavaria in summer and you'll still see this special look. i used to have some german pals big into metal that used to wear the classic 80's rock mullet and actually have another mate now - Ronnie -who sports a rats-tail mullet with moustache handlebars !! i think his wife likes it...
i have a book at home which is a quality reference on this subject:
The Mullet: Hairstyle of the Gods
if you want to borrow it just let me know !
