This is the original version of this song and viewer comments on YouTube seem to be unanimous in calling it the best. I have to agree. I think Fred Astaire's voice is often underrated, but it just hits the spot perfectly. I mean, he does something where it's like he's circling just on the edge of hitting a spot. And Ginger Rogers' face is so warm and open--even as this seems to be him trying to entice her, there's something subtle about him that's tantalisingly just out of her reach. She can't hold anything back, and he can't lay everything bare. Their movies don't always take advantage of that dynamic, but, boy, when they do . . .
