I'm in the ATC and I've known OF this song for a while but I don't have the lyrics to it. It's called Rambo and to my memory it starts something like this:

I'm gonna tell a story,
A story that seemed so real.
About a veteran warrior,
Who's name I shall reveal.
Ramboooooooo!

(I also remember a version made called 'Strongbow', if anybody has that I'd be grateful also!)
