I always get one man in the crowd who shal be left nameless who is bellowing for an " irish " song. I got fed up with the old coot one time and let Bean Phadeen go ........... in irish gaelic. The dirty beggar gets up then and tells me "That's not Irish!" Nearly losing it then and being restrained by my bandmates he then pipes up and asks for the Unicorn ( written by a jewish man no less ). The man in question was then told in no uncertain terms that any further disruptions would result in the band leaving the stage so the rest of the crowd shut him up. Until the next gig. Some people just never learn do they?
