Here's what we sang.

MIDNIGHT ON THE OCEAN

Tune of verse: I don't recognize any source. Will try MidiText. Tune of chorus: Stars & Stripes Forever March

1. Twas midnight on the ocean
Not a streetcar was in sight
The sun was shining brightly in
The middle of the night
A barefoot boy with shoes on
Stood there sitting in a tree
And as I put my glasses on
I heard this melody:

CHORUS
Be Kind to your web footed friends
'Cause a duck may be somebody's mother
Be kind to the denizen of the swamp
He's a "Dilly" through and through
You may think that this is the end,
Well it isn't cause there is another chorus.

... There may have been other verses, but I think one just repeated the first verse ad nauseum. When you got tired, you changed the last lines of the chorus to read,

You may think that this is the end,
Well it is.
