Jack Kyle says his Grand Slam heroes of 1948 are delighted to finally concede their unique place in Irish sporting history.
Ireland completed their first clean sweep for 61 years by bringing the 2009 RBS 6 Nations to a gripping conclusion with an epic 17-15 victory over Wales in Cardiff on Saturday.
Joyous scenes greeted the team's return to Dublin as fans, having witnessed some tortuous near misses in recent seasons, toasted the greatest prize in European rugby.
Kyle, 83, widely considered Ireland's best player of all time and the inspiration behind the nation's only other Grand Slam-winning side, was only too happy to join the celebrations.
"Seeing the players jump for joy and parade around the pitch was a pleasure," said the former fly-half, who attended the match at the Millennium Stadium with his son Caleb.
"I'm so happy they have won and taken on the mantle, more so because they are a side worthy of the Grand Slam.
"Many of them have been playing for a number of years, becoming a Triple Crown side without claiming the final prize.
"Some of them will be retiring in a number of years, and to do so as Grand Slam winners will give them enormous satisfaction.
"When they're old and grey they'll get together much like we have done and will be invited to functions as Grand Slam winners," Kyle predicts.
"We had that pleasure for a long time, and there is no regret whatsoever that they've joined us.
"After such a long time without the Grand Slam, we're all feeling proud that Irish rugby has achieved this.
"To win in Wales is always difficult, and I think that adds something extra to it.
"It's good for Irish rugby and good for the nation as well - people will have taken a lot of pleasure from this during difficult times.
"With all the different sports in Ireland, such as hurling and Gaelic football, it's good that we can still produce a Grand Slam side."
