Irish rockers U2 are in Dublin today to sign copies of their new book.
Their appearance, expected at around midday has forced the closure of Easons on O'Connell street from 8.30am until 3pm this afternoon.
Fans from home and around the world queued overnight, but only those with special wristbands will be able to get inside and meet their idols.
The book, U2 by U2, costs €32.99 and is expected to become a best seller.
