Is this a trick question?
They have been kinda going back and forth between retiring or not. From what I hear they have finally decided to call it quits (atleast in the US) and this is supposed to be their final tour. although they are schedualed to do an encore perfomance here next year for the people who didn't get to go due to the snow storm we had.We saw Riverdance in Charlotte, NC last year and they were billing it as their final tour of the US. Glad they're still touring. It was an awesome concert!
