I'm not sure that's a fair comparison. Crowd behaviour expectations at a football festival are very different to what local public / police / bar owners expect during normal periods.
I'd have been horrified if some of the behaviour of some Irish in my train carriage on the way to Sopot was repaeted outside a football tournament. In the context of a football tournament or any football game what would be considered yobbish in other circumstances is part of the event. But in a football tournament you expect singing and boisterousness and it's actually to be welcomed as long as a line isn't crossed over into threatening, rude or violent behaviour. I saw a lot of very drunken but equally harmless behaviour over in Poland.
According to the Indo here's what the locals thought of us:

Edit: just read the Fanning article. I have to say it did strike me that my time has come and gone. I would have no appetite whatsoever to do the amount of drinking some lads got up to and though I like my drink I don't like drinking more just for the sake of it.
