The intro had me imagining a set of players stepping up to the microphone: first the mandolin, then the dobro, then the fiddle gets a lick, and finally the piano player plays his bit and the singer shoos them all away so he can start singing.

The entire song goes that way, fitting in the various instruments like a jigsaw puzzle with every instrument filling in, but feeling very organic.
The Oooohs and Aaaahs are subtle - I went back and listened for them when I noticed you used them, and there they were.
Sparkling production all around, nice lyrics, well sung. Sounds great in my headphones.
