It's not folk, but I just heard it on the radio the other day for the first time in yers and I still like it: Johnny Mercer's "Autumn Leaves" sung by Nat King Cole....The autumn leaves drift past my window....

One of my favourite memories of growing up was hearing my grandma, then my mom read the poem When the frost is on the pumpkin. Having grown up in Wyoming and Colorado, where there are not a lot of pumpkin patches, the full meaning of this poem was realised by me after moving to the Berkshires of New England and driving by beautiful & huge patches of the biggest pumpkins my children and I had ever seen.

I posted another song in the Tavern Aftermath thread, "Who Were the Witches" which I always sing this time of year. I love fall, too!
