The tune to which Be kind to your web-footed friends is usually sung is John Philip Sousa's The Stars and Stripes Forever. Although, I'm sure anything is place. The original lyrics also by Sousa, first stanza, are:

Let martial note in triumph float
And liberty extend its mighty hand
A flag appears 'mid thunderous cheers,
The banner of the Western land.
The emblem of the brave and true
Its folds protect no tyrant crew;
The red and white and starry blue
Is freedom's shield and hope.

The water fowl lyrics are usually attribed to Fred Allen, the late, great comedian.

The Battle Hymn of the Republic provided the tune for a great set of lyrics that all kids hold dear to themselves:

Mine eyes have seen the glory of the burning of the school:
We have tortured all the teachers; we have broken ev'ry rule.
&c.

Ceci n'est pas un seing.
