The Flanders and Swann Hippopotamus song is also great. It is in Rise Up Singing, and I may be able to pry music out of my husband who wrote it out for a concert (he also wrote out the gnu song.) I also have the Leon Rosselson book around somewhere, Andy's Front Hall carries it, and it is a great one.

Bob Franke did a terrific song called William the Streak about a greyhound who is adopted and moves in next to a sheep farmer. The two come to a remarkable agreement.

Leather Winged Bat is nice.

Stewball on the Horse front

I suppose the Stan Rogers Doberman Disaster [Woodbridge Dog Disaster] would be right out, but it is a lot of fun.
