In 1946, he becomes a full-time freelance sports commentator, working for Radio Éireann, Ireland’s national broadcaster. In 1950, he begins presenting programmes for the BBC, being particularly well known for boxing commentaries, and soon becomes one of television’s most popular presenters. He begins hosting the game show What’s My Line? in 1951.
Throughout the 1950s, he commentates on the major British heavyweight fights on the BBC Light Programme, with inter-round summaries by W. Barrington Dalby. On January 20, 1956, he reaches No. 18 in the UK Singles Chart with a “spoken narrative” recording named “The Shifting Whispering Sands (Parts 1 & 2),” which is produced by George Martin with musical backing by the Ron Goodwin Orchestra. The song later reappears on Kenny Everett‘s compilation album The World’s Worst Record Show, which is released in June 1978.
Between 1955 and 1964, Andrews presents the long-running Sports Report on BBC’s Light Programme, now Radio 2. In 1965, he leaves the BBC to join the ITV contractor ABC, where he pioneers the talk show format in the UK. He hosts a chat show on ITV, The Eamonn Andrews Show, for five years. He is known for coming up with off-the-cuff linkings that do not work such as, “Speaking of cheese sandwiches, have you come far?” This is parodied by the character Seamus Android on Round the Horne in the 1960s, performed by Bill Pertwee. In the 1960s he presents Thames Television‘s Today news magazine programme.
Andrews is probably best known as the presenter of the UK’s version of This Is Your Life, between its inception in 1955 and his death in 1987, when he is succeeded by Michael Aspel, who had also succeeded Andrews as host of Crackerjack more than two decades earlier. Andrews becomes the very first This Is Your Life subject on British television when he is surprised by the show’s creator, Ralph Edwards. Andrews also creates a long-running panel game called Whose Baby? that originally runs on the BBC and later on ITV. He is a regular presenter of the early Miss World pageants.
Andrews’ chairs the Radio Éireann Authority, now the RTÉ Board, between 1960 and 1964, overseeing the introduction of State television to Ireland and establishing the Irish State broadcaster as an independent semi-state body. About this time, he also acquires a number of business interests in Ireland, including recording studios and a dance hall.
After months of illness during 1987, originally caused by a virus contracted during an airline flight, but which is not recognised at the time, he dies from heart failure on November 5, 1987, at the age of 64, at Cromwell Hospital, London. He had recorded his last edition of This Is Your Life six days previously on October 30, 1987, surprising Crossroads actress Jane Rossington. After his death, the show, and two others that have yet to be broadcast, are postponed until, with his widow’s permission, they are broadcast in January 1988. His widow, Gráinne, whom he married in 1951, dies 18 months later. They had three adopted children.
His contribution to U.K. radio is commemorated in the The Radio Academy Hall of Fame. Andrews appears as the linking narrator who introduces the unrelated segments that comprise the portmanteau film, Three Cases of Murder (1955).
