How about 'Pills' or 'Cholesterol', both by Glaswegian Adam McNaughtan? And 'Cod Liver Oil' (the one without the Orange Juice - the music hall song made popular by The Dubliners)?
I'd love to know which songs Clarke chose and how the students reacted to them!

BTW, the 'Burke and Hare' song Iamarca quoted far above was written by Robin Laing.
