Everyone knows this song because so many people have covered it. In fact - I dont think I have ever been to a music store where someone wasn't playing the melody to this song. Bill has an absolutely incredible catalog for a guys who's name you don't hear very often. It starts off slow and low and then builds up to his beautiful "head voice". If you listen just right you can hear every R&B singer who has come since him. Bill was the real deal - something that is missing from the heavily produced R&B/Pop music today.
I love how at the end of the song he gets up from the piano and reaches in his pocket for a guitar pick - such a talent!
