Nature-inspired music? (not environment-related)

I am a mole and I live in a hole.
The ugly duckling.
There was an old lady who swallowed a fly.

Arthur Askey recorded a series of invertebrate-themed novelty songs, but this golden age of British popular music came to an end with the arrival of a four-piece Liverpool band in the early 1960s. Despite a promising name, they did little to promote public appreciation of Coleoptera and promulgated an unfortunate mis-spelling. Their four contributions to the genre involved a blackbird, a walrus, a raccoon and cephalopod habitat, but all four songs are mainly remembered for their lack of natural history content.
