People go on about us nicking other teams chants, but we've had a few of ours stolen as well. "We're coming for you", "we're taking the p*ss"...fair enough the tune isn't original but these are all chants that didn't exist before we started them, and are now commonplace among a lot of teams.
I also don't think it'll be long before someone else comes up with a chant to Amarillo.
