It’s a wonderful life… if you can find it…
I was first introduced to this song when I heard Jerry Garcia’s version. But it’s an old, old, very old song. as old as 1656. Tom Waits has a version on his Orphans album. This version, by Gillian Welch and David Rawlings, gives it the respect it deserves.
