The Secretary of State for Northern Ireland Dr Mo Mowlam is a brave woman. Not only for entering the Maze prison and standing up to extremists of all hues but for venturing on the Gay Byrne Show on Thursday morning during her visit to Dublin. It must have been mentioned to her by the mandarins in the NIO that it was his encounter with Gay on the Late Late Show in January 1992 that brought down one of her predecessors Peter Brooke. But then she didn't sing.
