This is "Corduroy Road" which he wrote and sings on the Nitty Gritty Dirt Band album "Workin' Band." It's a good album and on Spotify, if you're interested.

His vocals on this are really good, and of course, the NGDB are premiere musicians, so you've got a good combination there. Just thought I'd share it since I've only seen it mentioned once on his threads.
