I was listening to this tonight, and sought out to make a chord progression in the Key of C to play as a duet for fun. I finished it, but it didn't come out in a beautiful recording, but I want to hear some feelins on it, please.

Author of the original song is Hoagy Carmichael, based on.
Chords: C major, A minor, F major, G major.
Rough recording, by the way.
