yes, for people from further afield, the term 'plastic paddy' normally applies to people doing unpleasant and unnatural things to Irish songs, in modern pubs that have been decked out to look 'authentic' for the purposes of luring in tourists. There's good money to be had doing plastic paddy, or so runour has it, which is why a lot of people get sucked in. I think the name probably also covers that really trite 'easy listening' kind of recording you get where decent songs are turned into lifeless mush.
