A solid line-out from the Welsh, sending the forwards rumbling... inch by inch, towards the whitewash they go... Gareth Davies pops the ball to Alun Wyn Jones with the posts in sight, but the lock cannot gather in full flight. Opportunity missed. A sigh of relief from Scottish fans. 

A fabulous driving scrum from Wales, Scotland pop up like toast and referee George Clancy has little option but to award the hosts a penalty. Dan Biggar with a wonderful touch-finder, the home team into opposition 22.

"There seems to be no reason to me for the decision to risk Dan Biggar. It is a long tournament and Rhys Priestland came on and did well last week."

Oof! Richie Gray nicks possession, the ball finds Stuart Hogg and the elusive full-back goes pumping and snorting down the left wing but is ejected into touch by Gareth Davies. A crucial tackle by the scrum-half otherwise it would have been an early Scotland try. 

Toot! That's the sound of George Clancy's whistle by the way. Dan Bigger gets the match under way and Liam Williams gathers and gallops down the left wing. Wales immediately on the front foot, home fans in full song already. 

Simon and Garfunkel, Astaire and Rogers, salt and vinegar, Roberts and Davies…

The duo are back together for this year’s Six Nations – the hex on Welsh centres having seemingly disappeared – and the return of the Clermont centre against Ireland after nearly a year out gave Gatland’s men more elan in the backline, though admittedly there were no line breaks against the Irish.

Only three other pairings stand above Roberts and Davies in world rugby - Brian O’Driscoll/Gordon D’Arcy (56), Ma’a Nonu and Conrad Smith (55) and Will Carling/Jeremy Guscott (45).

According to Wales defence coach Shaun Edwards,, external Davies and Roberts is a partnership that will be “talked about for the next 25, 50 years.” Much like Astaire and Rogers, but for their bulldozing than ballroom…

Head cap? Check. Jamie Roberts to the left? Check. Jonathan Davies will be raising his bat at the crease in acknowledgement of his half century, or something like that, as he wins his 50th cap for Wales.

Just as an aside, 41 of those caps have come with the granite-jawed Jamie Roberts by his side in midfield. 

The centre leads the team out onto the turf to warm applause from the fans.

"New sponsor, new name... same pre-match discussion about the roof.

"Two years ago when Wales beat Scotland 51-3 the match took place under a closed roof while the rest of Cardiff bathed in warm spring sunshine.

"It's thermals not sunscreen that are required today. Closing the roof is unlikely to make it warmer, but at least it will keep the rain out - and the noise in."

A "miraculous recovery" is how Wales head coach Warren Gatland described Dan Biggar's return to fitness after the outside-half hobbled off against Ireland with a sore ankle. 

Gareth Anscombe replaces Alex Cuthbert on the bench in the only change to the matchday squad which drew 16-16 against Ireland. 

The teams are lining up in the corridor, Jonathan Davies closes his eyes, takes a deep breath... Michael Sheen is in the crowd, as is Gareth Edwards...

There's been a late change to the Scotland line-up, with Sean Lamont taking the place of the injured Sean Maitland. Lamont offering plenty of experience, but the absence of Maitland will be a blow to the visitors.

More from Scotland head coach Vern Cotter: "I think coming down and believing you can win is important. We want to keep our shape and put on pressure for longer periods so we do better than last week.  It will be fast, furious and very physical."

Battered and bruised, and having to regroup after an opening Six Nations defeat. 

Scotland have become accustomed to rallying after starting the Six Nations with defeat. The Scots made more metres then England last week, carried the ball more, beat more defenders, had more line breaks and made more tackles, but still they lost.

What has been the response? Head coach Vern Cotter says: “This group have worked exceptionally hard this week to improve their accuracy under pressure. As a team we know we can perform better and believe we're capable of making improvements all over the park.”

The roof has been put into action at the Principality Stadium. Yep, the Millennium Stadium is no more. Well, it is, but it went to the deed poll office after the World Cup and changed its name. 

It could have been worse, there's a man ins south Wales who has changed his name to Romeo Brooklyn Beckham... 

Anyway. The choir is in full voice, Sosban Fach reverberating around the grand arena. 

I don't want to harp on and there's no way of wrapping this up in cotton wool because Scotland's recent record against Wales is a dismal one. 

During the Gatland era, Wales have won eight matches on the trot against the Scots. Indeed they've not lost since the New Zealander took over in January 2008.

Wales have Lazarus, external calling the shots at outside-half, so they say, with Dan Biggar having made a “miraculous” recovery from the injury that ended his match against Ireland abruptly.

But if a team needed to discover the ability to rise from the dead it’s Scotland, particularly against Wales, because it’s been some time since the Scots beat Wales in Cardiff. 

Eight defeats... Fourteen years of losses... Since Scotland last beat Wales, Britain has sent a man to the moon, Facebook has been invented and Westlife are just hazy memory of key changes and dodgy suits.

Can the Scots finally get one over Warren Gatland? Let’s find out.

Hello! Aimee here. Still awake? I think it's ok to say you can flush the memories of that match in Paris down the toilet of your brain. 

Hopefully we're set for 80 minutes of wonderful rugby in Cardiff.

That's all from our first game, next up try-shy Scotland travel to a Wales side still smarting from their draw in Dublin last time out.

To guide you through the action, here's Aimee Lewis...

"Once France made changes in their front row they were on top and dominant in the scrum. The damage really started there and France started to believe."
