Try Bob Franke's "Thanksgiving Eve" for a positive but thoughtful song. It should be in the DT but I'd be happy to provide lyrics and chords if it's not. Sally Rogers and Priscilla Herdman do nice renditions of this on their CD's. A friend of mine from Michigan, Camille Vetraino, added another verse, as have many others, which runs:

Each moment will pass like winter into spring,
Quickly enough on its own,
But a memory's made in the weaving of a day,
So let not a thread slip the loom.
