Doris Day does an excellent version of this song. I was surprised at how soulful she sounded. Of course, Nat was the ultimate in romantic crooners. I also liked his version of ‘The Very Thought of You’. He could have spoken than song vs singing it, and I still would have been taken in by his clear pronunciation, baritone verging on tenor, and dulcet tones.
