One of the fun surprises I have had recently is to discover mathematics in the lyrics of a once-popular song -- in "Ray's Dad's Cadillac" by musical legend Joni Mitchell, recent recipient of the Library of Congress Gershwin Prize for Popular Song.
Joni Mitchell -- who has recently come back to the stage after serious illness -- has surmounted barriers to female achievement and recognition as have many math-women. She has indeed "looked at life from both sides now" . . . Below I offer two mathy stanzas from her song -- "Ray's Dad's Cadillac." (The complete lyrics are available at this link).
