Joe Duffy couldn't have been happier to have Gay Byrne launch his autobiography, 'Just Joe', in Harry's Bar, Dublin, last night.
They first met in Christmas 1966 when Joe, then aged 10, got Gay's autograph.
Big names at the launch included Pat Kenny, Ryan Tubridy and Marian Finucane.
Describing the memoir as a "damn fine book", Byrne recounted anecdotes from their years working together in RTE.
In one of the most touching passages of the book, the 'Liveline' presenter reveals how himself and his fellow RTE stars, Pat Kenny, Dave Fanning and Ryan Tubridy, had been comforted by Byrne following a 'Late Late' tribute to the late broadcaster Gerry Ryan on the evening of the day he died on April 30, 2010.
"Gay was brilliant that night, like a father figure to us all: calming, reassuring and eventually just melting under all the emotion.
"Gay can come across as tough sometimes -- he is reluctant to visit hospitals or go to a funeral -- but that night he again proved that wisdom comes with age. He truly is a remarkable man."
Earlier, guests had been invited to travel on the O2's big wheel, where they heard Duffy's voice giving them a tour of the sights of Dublin.
