Jay, I also saw David Francey play an intimate show in early 2016, and was fortunate to have the opportunity to have a brief chat with him after the show.This guy is really fascinating. I saw him six months ago at the Stone Church in Newmarket, New Hampshire. He tells funny anecdotes before each song, each story lasting several minutes. Very entertaining.
Not sure if he plays any instruments. Mostly writes lyrics and sings, from what I could tell.
I asked him if he plays an instrument while composing, and he said that he doesn't really play guitar enough for that,
and that the melodies are mostly developed by singing the lyrics "a capella" solo, and also bouncing them off the members of his band.
The following video is representative of the performance that I saw, minus the always interesting rambling introduction he gives each song
