A colleague was whistling the marching tune one hears in The Bridge in on the River Kwai, and after I asked him if we were suddenly in the British Army, I wondered what the name of the song was. Luckily, there’s a way to find such things out, called the internet (which is apparently a series of tubes.) Turns out it’s called The Colonel Bogey March, and the Wikipedia entry implies it has some interesting (not G-rated) lyrics, which it does.
