U2 frontman Bono wants be remembered for his contribution to rock music instead of his political activism.

The 45-year-old singer has been a key figure in raising awareness of AIDS and poverty in Africa and campaigning for the elimination of developing nations' debt.

But the modest 14-time Grammy-winner would prefer to be recognised for role in his Irish rock band, because he hopes the global issues he has campaigned against will be solved by the time he passes away.

He says, "I think my work - the activism - will be forgotten. And I hope it will. Because I hope those problems will have gone away."
