The following Annual Report recorded:-
"In the ninety odd years of its history, the club has been extremely fortunate in the large number of its members who have given voluntary service in many directions. Only those who are involved in the inner workings of the club which covers so many playing activities and a large social centre, can appreciate how much it depends on the loyalty and sacrifice of such members. Vince Griffiths was a wonderful example of a man who felt all this was worthwhile to a club which he said on many occasions had done so much for him."
"Much has been said of his contribution to Welsh Rugby and there is no doubt that his great knowledge of the game and his refusal to be stampeded into any decision, unless he felt it was in the interest of the great amateur game he loved, gained the respect and affection of all with whom he came into contact."
"Within our own club his contribution to the Rugby side is well known. As a player he was captain in the seasons 1927-28 and 1928-29 and a member of the British Lions team that toured South Africa in 1924 and as would be expected of a player of his ability, a Welsh international. His wisdom and prudence played an integral part in maintaining the Newport Athletic Club as one of the great institutions of both town and county. His outstanding attribute was his absolute integrity; his word was his bond. He never forgot a promise and one could always rely on a confidence which placed with him would never be disclosed."
