With JSngry's recent excursion into the work of Billy Eckstine, I revisited this video of a performance from later in his career. I love the performance and I love that he is wearing pretty much the same tux I wore to my high school prom about 10 years later (it looks much better on him!).
You can really feel that "long, hard climb" the way he sings it. And he must have been about 55 by this time, but I bet he still was a powerful chick magnet with his looks, style and voice!
