This is what I'll refer to as a complex love song. He was on the road.
Well, I think everybody does. His cover of it was so revolutionary that I think from that point on it became his song. But it had been a Tin Pan Alley standard — everybody had recorded it. And it's a sentimental song, and what Otis did with it was he transformed it musically.
He begins by singing the song the way everybody sings it, as a slow ballad. And slowly, over the course of the opening verses, the instruments come in and the rhythmic intensity of the song starts to increase. Then, at a certain point, it moves from his original métier, which was the 12/8 ballad, into a ferocious, 4/4, stomping groove. And at that point, of course, the whole tenor of the lyrics change. It's a song about tenderness, but there's nothing tender about the way Otis sings the last few verses of the song.
