I thought it was an instrumental until it wasn't.

Then I remembered that Waylon used that technique a lot, especially in his live shows ( not on TV ) play a verse and a chorus then start the vocals..... it stretches the song for a live show... that equates to having to learn or play fewer songs.... like the time our band was hired to play a 4 hr gig after we won a battle of the bands talent show. We were brand new, and while we were good..... we only had 7 songs on our set list at the time. Yeah that made for an interesting night.

Back to your song.... organic and off the cuff comes to mind. I like the feel on the song
