Col, I enjoyed the chord changes. Very good, I do this tune also with a Lawrence Welk type style. I'm going to do it with a Bossa style like you also. My ear bent just a bit on the bridge on the vocal melody. You're playing the correct changes, so I'm wondering why you change the melody with your singing. Perhaps you're working around the higher notes. I play this in Eb but I transpose it to Db. It is one of the harder tunes because the melody range is wide. I have the same problem with Friends In Low Places and I've Got You Under My Skin. The melody note's range is wide on these two tunes also.

I enjoyed this very much. You have a nice voice and you do sing in tune. Bravo
