Who is the sexiest female vocalist?

Kubla, by chance I picked an old record of Frankie Boy last night and man, what a voice--so my vote for male Viagra goes to Sinatra....female...Betty Holiday and that by a margin. Cheers to all,

SHHH Kubla, right...defenitely Tom Waits as well....how could I have forgotten...Bwana was not there....Big cheers to you!PSSSSS
