For anyone wondering, that song in the middle is "Five Long Years", best known as an Eric Clapton cover in the 90s, although the original is much older. That's definitely me singing, but I think the harmonica you hear is another player. It was recorded a few years ago, so my memory is spotty, but I recall there being a quite large ensemble on stage that evening, including an electric violinist named Lionel Young (he is AWESOME) and a second harmonica player in addition to myself. I did play on that song, but my solo was much earlier in the 13-minute track.
The second song you'll hear, near the end of the episode, is Ty Shughart's "More and More" from his days as King of the PGC forums.
