The radio presenter and Eurovision host revealed the queen told him she tuned in to his long-running breakfast show before yesterday’s ceremony.
“She is one of Terry’s Old Geezers, although anybody who had the nerve to call her that would be very, very foolish,” Wogan joked.
A Limerick native, Wogan has dual citizenship, allowing him to have a regular knighthood and use the title ‘Sir’.
“I’ve got two badges. It means my wife can use the title of Lady,” he said.
He said he was “delighted” to have been knighted.
“As an Irishman I’m doubly honoured to receive this not in the country of my birth.”
Wogan was born in Limerick in 1938 to a grocer father and a mother, but “the great move to Dublin” occurred in 1956.
He began his career on Radio Éireann and by the 1960s was a household name. His BBC Radio 2 show, Wake Up With Wogan, attracts more than eight million listeners a day.
Mayor of Limerick Diarmuid Scully said the honour was well deserved.
He said: “We are very proud of him and he has always been a great supporter of Limerick and keeps in touch with his old friends in the city.”
