I can't imagine it as a rock song. It was done by Karrin Allyson on her In Blue cd. She is a jazz singer, though. It was written by George and Ira Gerhwin... at least her version.
Thanks, Drubin. You nailed it. John, I'm not sure if this is the Gershwin tune or not, but the Ace recording is the one I'm after. I was very impressed with the depth of the sound, even coming through the FM radio. I'll have to look them up and see what other hits they had. If this is the only good one I'll probably just score the CD.
