OK, so calling it a world cup is stretching the truth rather, but..
England played Tonga the other day in New Zealand. With seven minutes left of the eighty England were winning 20-0. All over, you might reasonably suppose. Not a bit of it.
Tonga suddenly caught fire and scored three converted tries in five minutes! 20-18! And had what would have been the winning try ruled out in the last ten seconds!
Fantastic entertainment - but for me the best moments were the largely Tongan crowd singing the songs of their homeland. They were truly beautiful and made this soft old sod well up.
The match should till be available on BBC I player and is well worth a look.
