I am not really out of retirement, but I saw this on Tor and had to share, for those who haven't already seen it. (Maybe it's all over the f-list; I haven't looked.)
"The Ballad of Hollis Wadsworth Mason Jr," by Franz Nicolay (of the Hold Steady).
Yeah. So. It's about Hollis Mason, and it has an accordion, and is pretty great, I think.
