I always think of this song as fall goes on:
"The falling leaves drift by the window
"The autumn leaves of red and gold
"I see your lips, the summer kisses
"The sun-burned hands I used to hold"
"Since you went away the days grow long
"And soon I'll hear old winter's song
"But I miss you most of all my darling
"When autumn leaves start to fall"
(Song by Johnny Mercer, my mental jukebox plays the version from Midnight in the Garden of Good and Evil. He based it on a French song, apparently.)
