This came up on random shuffle on my iPod the other day and I've been meaning to share it since. It is one of my favorite tunes of the era, but surprisingly was not one of Sylvester's bigger hits. To this day I can't understand why.
I agree 100% with the comments left by a guy who posted a slightly shorter version of this on YouTube:
There have been many "classic" versions of this tune done by many artists over the years (from Shirley Bassey to Tom Jones, and more), but in my humble opinion, nothing comes close to the emotional resonance of Sylvester's version. Astounding and brilliant, it brings tears to my eyes, not only because of the beauty of his voice, but also because it was a such a special time period that will never be repeated. It didn't matter who you were or what you were. Everyone loved Sylvester.
