Yes, there may be two. this is the silly one.
Here's song ONE that was in my head on Friday:
Dance your cares away,
Worry's for another day.
Let the music play,
Down at Fraggle Rock.
(If you don't know that song, you missed out!)
GENERAL: I am the very model of a modern Major-General,
I've information vegetable, animal, and mineral,
I know the kings of England, and I quote the fights historical
From Marathon to Waterloo, in order categorical;
I'm very well acquainted, too, with matters mathematical,
I understand equations, both the simple and quadratical,
About binomial theorem I'm teeming with a lot o' news,
With many cheerful facts about the square of the hypotenuse.

Hm. OK, I can't remember song three. But there WAS a third one. :)
