Fact of the matter is lads (and lasses), if people start singing this one, are you going to sit in silence and go "I'm not singing that, it's shite"?
Whatever catches on, will. Doesn't matter about individual people really. If enough of the support choose it then you're fucked if you don't like it. The Gerrard one is absolutely shite, but what can you do?
So just wait until this (or whatever) takes off and go along with the ride. Just make sure it isn't fucking ABBA.
