Ann is my top female singer hands down. I remember the night the lead player in the band I was in, played the Dream Boat Annie album. I played it over and over all night.
Nancy can hold more than her own against most guitar players rhythm and lead as well. There is a few good videos on youtube of her and Ann going for it.
One thing I love about Ann is most female singers hit notes that seem to loosen the ear wax from the in side of my ears. Ann's voice has never done that at any volume, then mix Nancy's voice in there.
