Bett Midler the divine miss M has to have one of the greatest voices around.
Not only can the girl sing she can act and put on shows that were way ahead of anything Madonna tried to do( and Im not talking vocaly. Madonna has a poor Vocal range in comparison to singers. )

Barbara Sriesand WOW.

Joni Mitchell absolute cracker.

Female vocalist with Cappercailie cant think of her name. Shame on Me.
