I like a lot of the songs mentioned above, Urge for Going, Who Knows Where the Time Goes, Fall is Here, Turning Toward the Morning, etc.

Ann Dodson (sp) was in a group that did a lovely one called Lie Easy. I also think of Bok's Hearth and Fire as being an autumn song.

I wrote an apple round a few years back.

Cortlands and spies in the fall of the year Baked into pies or for eating Sweet as summer's last sun, crisp as winter to come. Cortlands and Spies.

I have always loved autumn. It has meant apple picking, Red Sox baseball (GROAN) the lovely slant of autumn morning and evening sunlight, the colors that Vermont produces in wild abundance (I've lived here for over 40 years and I am surprised every year), those crisp nights when you go out under burning, close-set stars and blanket the tomatoes, and finally, the free-for-all tomato fights once the garden was well and truly put to bed. Thanks for starting this thread.
