Bette Midler's most recent album is Bette Midler Sings the Peggy Lee Songbook. My favorite song on it is "Fever." Here's a live performance on the Today Show (start playing it at 1:30 if you don't care for Katie Couric):
I've had this song (by Jerome Kern and Oscar Hammerstein) in my head lately. It was originally written for the musical, Very Warm for May,* but it's been recorded by countless musicians since then. I had a difficult time picking which YouTube video to feature, but Judy Garland's turned out to be one of my favorites.
* Stephen Sondheim saw the original production of Very Warm for May when he was nine. He says that that performance was one of the things that inspired his interest in musical theater.
