Who's Joan Jett, and fanny..... lol. fanny means something other than your backside or the spirit of a woman watching over them (as they say on their website...) here in the uk it means something else. (hint... ladies front bottom... cough..... ) ;-)

Is this an American thing,never heard of them, here in the Uk the first female rock band i remember was Girls school who i believe started out as a supporting band for motorhead (i think) which was back in the 70's, i remember them always being in the charts and stuff when i was a randy testosterone filled teenager... ;-)
