Check out a song sung by Pete Seeger (I don't know who wrote it) called "Equinoxial," or perhaps "Equinoxial and Phoebe." (The women in your class will love it.) Or how about "Kisses Sweeter Than Wine"? Or the one that begins, "Inch by inch, row by row, gotta make this garden grow, someone bless them from below 'til the rain comes tumbling down...." (I'm sure the song writer is still alive and can claim it and finish it.") More later when my weary head clears.
