Taoiseach pays tribute to legendary broadcaster
Taoiseach Brian Cowen, who is renowned for impersonating the broadcaster, said O'Muircheartaigh is one of the most popular and admired figures in Irish life.
"He has had a long and hugely distinguished broadcasting career and he has brought pleasure and excitement into the lives of millions of GAA supporters," said Mr Cowen.
The Taoiseach also congratulated the presenter on his many achievements and great service to the Irish people.
"Micheal has contributed significantly to our understanding and enjoyment of great sporting occasions down the years," Mr Cowen continued.
"His enthusiasm, knowledge and passion for Gaelic Games are unrivalled.
"He is an unassuming legend and in many ways he has become a treasured national institution.
"He is also a great gentleman and despite his remarkable success, he has remained the most modest and gracious of men."
Fine Gael sports spokesman John O'Mahony revealed his favourite memory of the broadcaster was when he was commentating at the end of the 1994 Connacht Final where he spoke of Leitrim people watching "from the veranda of heaven".
"Micheal was as important to GAA matches as the football, the sliotar and the players," he added "His love of Gaelic football and hurling was there for all to see and hear and he was loved all over the world as well as at home."
