I've heard the Carmen version, which is pretty good, have not heard the Dionne version, but like Marvin and Tammy said, "Ain't Nothin' Like The Real Thing", and I'll stick with the original, especially that stunning extended wordless outro, which has always been my ultimate EWF moment. And I'll stick with McRae's "Great American Songbook" 2LP set on Atlantic from three years earlier, which is the other kind of Carmen McRae album, though I've always always liked the idea of her work more than the reality of it.
