Being an older fellow, I still love some of the singers from my youth, and consider them to be amongst the greatest:
Judy Garland
Barbara Striesand
Julie Bud
Doris Day
More modern Vocalists who I enjoy tremendously, with the right material:
Celine Dion (great voice, mostly lousy songs and interpretations)
Joan Osborne (this girl has some serious chops, imho)
Amy Lee
And of course, Janis.
Doris Day?You're letting your crank think for your ears. How I remember those fantasies, along with Haley Mills and Annette Funicello. :0
