Bono was unaware he had secret half-brother for years

The U2 frontman, who has an older brother called Norman, revealed on BBC Radio 4's Desert Island Discs that he didn't know about his father's other son for decades. "I do have another brother whom I love and adore that I didn't know I had, or maybe I did.” Bono on BBC Radio 4's Desert Island Discs. “It's a very close family and I could tell that my father had a deep friendship with this gorgeous woman who is part of the family and then they had a child and this was all kept a secret."
