Favorite Romantic Female Vocal Song(s)?


My favorite listening is romantic vocals by females. Usually these are Jazz or standards...ie: Diana Krall, Sarah Vaughn, Ella...and the list goes on. I know there must be gems out there that I am just not aware of....help me out here with your suggestions and favorites. Thanks!

Bette Roche on Bethlehem records 3 record set "Porgy and Bess". She is SOOOO sexy on "Summertime".
Lots of good suggestions here. I'd like to add Emmylou Harris, "Wrecking Ball". Also since it's almost Christmas, how about that Eartha Kitt song to Santa. And, Marilyn was the definition of romantic singing "Happy Birthday" to JFK.
