Happy birthday, Gay Byrne. The veteran TV and radio show host has created some of the most memorable moments in Irish broadcasting history.

“Late Late Show” and “Meaning of Life” host Gay Byrne celebrates his 84th birthday today! Born in Dublin on the date August 4, 1934, Byrne hosted the world’s second longest-running TV talk program, the “Late Late Show” on RTÉ from 1962 to 1999 and with catchphrases such as “once more with meaning” and “there’s one for everyone in the audience” he quickly became a national treasure.

Although Byrne retired from the Late Late in 1999, it has continued under different presenters and currently has Ryan Tubridy in the host’s seat. Only America’s “The Tonight Show” has run for longer on NBC since 1954. “Retirement” for Byrne didn’t mean the end of his broadcasting career as he still presented a once-a-week radio show on Lyric FM and a television interview series, “The Meaning of Life.”

Back in 2011, he was even going to take a crack at the Presidency and was a hot favorite to take over from Mary McAleese before removing himself from the race.

Bryne is most celebrated for the topics that he addressed on the “Late Late,” bringing subjects not previously so publicly talked about in a formerly more conservative Ireland into the main debate. Under Byrne’s stewardship and presentation, the "Late Late" became a forum where controversial topics such as the influence of the Catholic Church, contraception, AIDS, homosexuality, abortion, divorce and other hitherto taboo subjects were discussed openly in Ireland.

Byrne conducted scores of memorable interviews, including of Bishop Eamon Casey’s lover Annie Murphy and he once angered another bishop, Michael Browne, who called Byrne “a purveyor of filth” after he asked a woman what color nightie she wore on her wedding night, and she had replied that she believed she’d worn nothing.

Here’s a look at some of this most memorable moments:
