It has been my intention for some time to put together a tape of what, for want of a better description, I was calling Not-quite-Christmas songs. "Human" is probably more accurate, though it lacks pizazz. Although this may not be exactly what you are looking for, but, here are a few that I have slated for the collection:

The Anti-Carol (by Frank Poole?)
No Christmas In Kentucky (Phil Ochs)
Christmas In Prison (John Prine)
First Christmas (Stan Rogers)
Christmas in the Snow (Peter&Lou Berryman)
Christmas in NY (The Pogues)
St.Stephen's Day Murders (Elvis Costello)

Any others along these lines?
