Thanksgiving Music

Some people reject the idea of listening to Christmas music before October is over. Some people prefer to wait until the week before Christmas Day. But most people agree that sometime in November is a good time to start. What this author wants to know is that why isn't there lots of Thanksgiving music? There should be an entire industry dedicated to folksy songs of thanks and acknowledgements of the blessings of life. Technically "Jingle Bells" is a Thanksgiving song. It was written for that holiday by the artist but it was sort of absorbed by Christmas. "We Gather Together" is a nice one but complex and a bit difficult to sing. Not to mention very overtly religious.
So what are your favorite thanksgiving song?
