I don't have the words to gladiator, but I used to play for an American Football team called the Guernsey Gladiators. Also I sing with a shanty group called Jenkins Ear. One of our crew Jerry Cobb, does the Gladiator as a perty piece when he is the worse for drink, or is in high spirits. He's not on the net ( although he should be as he's a fih seller). You can contact him viaGuernsey Fish Supplies The Old market Fountain St. St Peter P{ort Guernsey Channel Islands UK
You could try Guernsey tourism (I think they have a web page, Jerry is fairly well known in the island).
Emial me back if you need more info.
