Listen, via RTÉ Archives: Ulick O'Connor On Brendan Behan (1970)

A popular guest on RTÉ's Late Late Show in the 1970s and 1980s, and an outspoken commentator on social, cultural and political issues, his memoir The Ulick O'Connor Diaries 1970-1981: A Cavalier Irishman chronicled his meetings with well-known personalities from politics to the arts.

In a statement, President Michael D. Higgins said: 'A voracious reader, with an obvious delight in the power of words, Ulick O'Connor became a well-loved and distinctive voice in public debate, and his prose, literary criticism and his own poetry will continue to be read by many generations.

'Celtic Dawn', published in the 1980s, was a valuable and provocative contribution to debate on the Irish Cultural Revival. As a biographer his works on Oliver St. John Gogarty were the source of his much appreciated one-man shows.

His commitment to performance will be remembered fondly as well as his lifelong support for actors and their livelihoods.

As President of Ireland, I extend my deepest condolences to his family, friends and all those whose lives he touched in so many ways.  I was proud to have him as a friend.'
