All great bands listed above but if there was a "best Irish band competition" surely U2 would win it?
They have been internationally succesful since early 80s, have sold 100mln+ albums, sell out stadium gigs of 60,000 within minutes, had the higest grossing tour with Vertigo last year, are the most influential, Joshua Tree was rated #2 best album in recent Top 100 albums thing on telly, coolest (well wouldnt you like to spend a night in your local with Bono or The Edge?).....
Although best looking are The Corrs (apart from the hairy bloke)....
