Good Welsh scrum but it rather crumbles. Biggar with the up and under and after a bit of pinball Wales win it back. Warburton goes on a barrel, Biggar kicks through, Medard tidies up for a 22 drop-out.

And we're off, Jules Plisson gets us under way... Liam Williams underneath it. France look to spin it wide but it's a forward pass to Camara on the left wing. Scrum Wales on the 10m line.

The French belt out LaMarseillaise with typical vim before we're treated to 70-odd thousand Welsh folk tearing into Land of My Fathers. And that's that, we'll have some rugby in a minute.

HRH the Duke of Cambridge, aka Prince William, is in attendance at the Principality Stadium tonight.

And he's has just had a chin-wag with BBC Sport's Sonja McLaughlan: "I love coming to the rugby. Having lived in north Wales for four years, I'm thrilled to be back again. It's great to hear the atmosphere. When you hear the anthem, you know you're in Cardiff."

Many thanks Michael, this is Ben Dirs. Players are out and we'll have some anthems in a minute. But first, we have a minute's silence for the victims of the recent cyclone in Fiji.

Winger Alex Cuthbert replaces Tom James in one of three Wales changes to the starting XV.

The other changes come in the pack, as flanker Dan Lydiate replaces Justin Tipuric and Bradley Davies stands in for injured lock Luke Charteris.

"Evaaar-moooore...Feed me now and evermore."

Right, as Bread of Heaven rings around the rafters, it is time for a check-up on the personnel on show.

Pete: Wonderful to hear "Dyma o Hyd" and "Calon Lan" ringing from the stadium!  

We may need to borrow a hymn sheet, Pete....

We have a full blown contest for the supporters going on here between the choir and the players.

The choir are on halfway singing their hearts out.

To their right Wales are going through tackle routines and away to their left France are practising their line-out.

At the moment, the singers are coming out on top.

"George North has no form for Northampton but instantly when he gets to Wales he feels confident and he scored a wonderful try against Scotland."

Thomas Castaignede
Former France international on BBC One

"Four months ago we lost a lot of pride over here in the World Cup against New Zealand. 

"It's not just about the winning. Every team wants to do the best on the pitch, and hopefully collect the trophy.

"It's going to be hard. The atmosphere is tough here."

Keep an eye out for the French substitutions this evening. If prop Vincent Pelo takes the pitch he will be the first rugby international from the Wallis and Futuna Islands. 

Where are they? In the tropics in the Pacific ocean belonging to the French overseas collectivity. They boast an annual average temperature of 26 degrees celsius.

Not like a cold Friday in Cardiff when the roof won't close, then.

"Warren Gatland feels comfortable with the surroundings, with the environment. They're totally relaxed and looking forward to the game.

"All the attention is on England. Eddie Jones has taken over winding people up, so Warren's very relaxed."

The roof is open so there's the unaccustomed whiff of fresh air inside the Principality Stadium, but in concourses and around the concessions there's the unmistakable whiff of pies, hot dogs and beer.

It doesn't matter whether the roof is open, or what day - or night - of the week it is. 

It's the Six Nations night. It's the happiest night of the week.
