U2 frontman Bono has accepted an honorary British knighthood at a ceremony in Dublin. The rocker - real name PAUL HEWSON - was joined at the ceremony by his wife ALI HEWSON and their four children JORDAN, 16; MEMPHIS EVE, 15; ELIJAH BOB PATRICIUS GUGGI Q, seven; and JOHN ABRAHAM, five; as well as bandmates The Edge and Adam Clayton. Bono received the award at British ambassador to Ireland DAVID REDDAWAY's official residence in the Irish capital. Like fellow Irishman Bob Geldof before him, Bono is not entitled to use the title 'Sir' because he is not a British citizen. He enthused, "You have permission to call me anything you want except Sir. Lord of lords, your demi-godness." British Prime Minister Tony Blair wrote a letter, praising Bono, which was read out at the ceremony. He wrote, "I'll leave it to others far more knowledgeable than me to talk about U2's music - all I'll say is that, along with millions of others right across the world, I'm a huge fan."
