Gareth Edwards was one of the many stars of the past who brought his grandchildren to see where he performed some of his greatest sporting feats and there were 800 people at the event.
"It was an incredible day and the buzz, camaraderie, warmth and humour was very special. It was an honour to be among the players who helped to make Welsh rugby great," said WRU chief executive Roger Lewis.
"So many players from so many different generations turned up and it developed into a real 'Who's Who' of Welsh rugby. The history and heritage of our national game needs to be celebrated. Most of these great players are very modest people and we need to properly recognise them.
"There was a fantastic range of players, from 90-year-old Gwyn Evans to current Cardiff Blues professional Chris Czekaj. It was an honour for me to say hello to the great Lewis Jones and it was marvellous having him and other former rugby league converts like Garfield Owen and Glyn Shaw at the event to show once and for all that all the old prejudices are very much a thing of the past."
Former Cardiff back row man Gwyn Evans won his first cap alongside Bleddyn Williams in the first official international after World War 11 in 1947. They were the oldest surviving players at the event and Jones still remembered the day he won his first cap.
"It was a huge honour to be picked to play for Wales and I can still remember running 40 yards to score a try on my debut. To me that was the highlight of my career," said Evans. "The Millennium Stadium is a magnificent place, quite different to the old wooden North Stand that had been damaged by a German bomb during the war."
There were 26 British & Irish Lions and 19 former captains of Wales among the exclusive gathering and a few stars of the future as well. The sons of Glyn Llewellyn and Mark Taylor won the kicking competition to prove the production line of talent is still in operation.
Other guests at the event were Liza Burgess and four members of the Welsh Women's rugby team, former international referees and ex-groundsman Bill Hardiman.
The former WRU Coaching Organiser and Secretary, Ray Williams, was also present.
