There are many Christmas songs but few Thanksgiving songs. In fact the only one I know is "Alice’s Restaurant Massacre" by Arlo Guthrie. It’s 18 minutes long, so I think that makes it count for five songs. (A big Thanksgiving thank you to Uncle Crappy for reminding me about the song, which seems to slip my mind from time to time.)
The song was such a success that they made a movie version as well. The movie has a rambling 1960s style, loosely edited and strange and goofy in a good-natured hippie style. If you know the song, you know most of the plot; the additional plot points don’t contribute much. But if you’re curious to watch you can fast forward through the dragging bits.
