I just had to think of this song, released originally in 1968, based on the old ballad of Lydia Pinkham. It praises the advantages of Medicinal Compound, whatever that might be.
Pink is not really my colour, I am more into blue, but I appreciate the odd pink flower I have in my front garden (a buddleia bush).
And, of course, who could not resist having a pink caterpillar for the heavy work. I mean the machinery of course, and not the insect.
