Long ago on CBS there was a newsmagazine called West 57th Think a younger, hipper 60 Minutes. The show didn't last, but they did have a piece on the band and their involvement with the Amnesty International concert tour. I'm hazarding the time to be between 1987 to 1989.
April 2001:Access Hollywood was interviewing Bono and Edge, mainly asking about Bono's upcoming involvement in the wedding of friend/supermodel Christy Turlington. The interview was at a famous L.A. hotel where The Doors' Jim Morrison often hung out to get drunk and dangle off the edge of the building. So Bono being Bono wobbily climbed onto the side railing of the balcony (I'm sure to the disapproval of his minders) and in a flat American accent said "I am the Lizard King," then looked at the bottle he was holding and murmured, "Oh, Perrier."
