I know that's a joke but he genuinely has a very international fan base, you should see ballyshannon on June Bank Holiday, it is choc a bloc with camper vans from all over Europe. I can't think of any other irish artist or festival that generates that interest , he may not have the U2 record sales but I doubt u2 would generate that interest, I know they did back in 80s and 90s but not now. Gallagher fan base is fiercely loyalThe biggest problem is that most of his fans are from Cork and Cork people are too mean to pay into a museum.
