I remember from my schooldays in the mid-1940s a record that ran:

Be kind to your web-footed friends
For a duck may be somebody's mother
She lives all alone in the swamp
And she never gets the cramp
Oh you may think that this is the end
Well it is"

sung to Sousa's Stars and Stripes


On British TV last night (Feb 10 2011) it was reported that King George VI sung something like this in 1936, although only the last two lines were transmitted
