The second link doesnt work any more. The chorus is the following:

We are, we are, we are, we are, we are the
    Engineers,
We can, we can, we can, we can demolish forty
    beers,
Drink rum, drink rum, drink rum, and come
    along with us,
For we don't give a damn for any damn man
    who don't give a damn for us.

This is a variant of Lady Godiva without the Godiva verses.
