An all-time favorite of mine, and no, there's nothing personal about my love for this song.
I wish that I could remember who said it, but I read a quote one time about old Chet. A big-time jazzbeau said, if I may paraphrase, what can you say when you listen to a guy sing, the guy can't sing for shit, but he sings the song and it makes you cry. That's Chet all over. He really loved these old songs, that was his secret. Sincerity counts for a lot in this singing game.
