Ireland's biggest rock star? I have a feeling I know who you're referring too, but I won't hazard a guess. Maybe he thinks that because we're living on islands here, it is easy to know someone famous. The reality is that it's not that easy. The most famous person I've eveer seen in the flesh was Sean Connery, and that was at the Punchestown horse-racing festival.
I don't know why but I'm getting the feeling that you're definately going to remain in contact with him for the foreseeable future. Maybe you just needed to come here to 'vent' your anger and frustration.
