Joe McGinnis quotes the song in his true-crime book Cruel Doubt (New York : Simon & Schuster, 1991), page 89:

His favorite, which she never forgot, was one he called "The Geography Song":

Maine is an island in Asia,
France is a river in Spain.
Coconuts grow on a mountain of snow,
Deserts are covered with rain.
Crocodiles come from Chicago,
Silver is mixed in a mill,
Grass is quite rare,
The equator is square,
And Kansas is south of Brazil.
