Bono takes part in a radio discussion about the art of singing. Following an extract from 'Out of Control', opera singer Veronica Dunne and singer and song collector Frank Harte give their opinions of U2's vocalist.

"Bono lead singer with U2 it has been said of you that literally you don't have a note in your head" is how Pat Kenny opens this part of a discussion on the art of singing. Taking part are Bono, opera singer Veronica Dunne and singer and song collector Frank Harte.

Bono says that the craft of singing in a rock band for him is about the portrayal of emotion and having something to say.

Having listened to an extract from 'Out of Control' Veronica Dunne tells Bono that he uses a "chest voice" that will be limiting to his voice range in the long run.

Frank Harte feels that excellence in anything including singing always come to the fore.
