There's a piece of commentary that rugby fans of a certain vintage know almost as well as they know their own children: 'Bennett ... chased by Alistair Scown ... brilliant ... ah that's brilliant ... the halfway line ... Tom David ... brilliant by Quinnell ... this is Gareth Edwards ... a dramatic start ... what a score!'
The commentator is, of course, describing 'that try' from the never-to-be-forgotten clash between the Barbarians and the touring All Blacks in Cardiff in 1973.
Watching it again 31 years later, the game is every bit as compelling, the passage of time having diminished none of the flair and spectacle.
And just as compelling is Cliff Morgan's commentary for the BBC. The Welshman, himself a former great at flyhalf for Cardiff, Wales and the British Lions knew a thing or two about the game of rugby and a thing or two about broadcasting, having been a reporter, producer and, for many years, the head of BBC outside broadcasts.
However, Morgan, in Hong Kong this past week as a guest of the Welsh Society, cringes at the memory of that call. He is now a septuagenarian and limping a little after a double hip replacement, but that mellifluous voice is present and correct.
He dismisses any suggestion that he made a vital contribution to a great occasion. 'I didn't do many commentaries,' he says. 'My voice was wrong. Bill [friend and BBC colleague Bill McLaren] had a more rounded voice. Mine was too Welsh and musical and ... sexy.
'Bill was ill with a sore throat or something and couldn't do the game. So I did it. [But] I didn't know what I was saying - 'the halfway line ... the 10-yard line' - my commentary was bad for television. And I regret saying 'what a score'. I should have said nothing. But it was a spectacular try. If Edwards hadn't dived from eight metres out he wouldn't have made it.'
