An before I escape back to 2015, let me direct you to some appetite-whetting content on the BBC Sport website - you've got the Calcutta Cup through the ages, this feature by Bruce Pope on six memorable Wales-Ireland Six Nations encounters, and a column by former Wales captain Gareth Thomas. I will bid you farewell.

England captain Will Carling: "That was the most amazing atmosphere I've ever played in. But we managed not to lose again in my time. In 1995, we had another Grand Slam decider and I was interviewed beforehand by a Scottish journalist. I could tell he wasn't fond of me at all.

"It got to the end of the interview and he said: 'How do you take the fact the whole of Scotland hates you?' I said: 'That's fine, because I hate you.' He dropped his pen and said:' You can't say that!' I said: 'Hang on - you can hate us, but we can't hate you back?' That's what frustrates me about being English."

Meanwhile, back in the real world, this Saturday sees England play Scotland at Twickenham, after Wales host Ireland in Cardiff. Both matches on BBC One and BBC Radio 5 live, and a host of other BBC outlets. All details elsewhere on the BBC Sport website.

Next Sunday, 22 March at 1900 GMT on BBC Two, you can watch Six Nations Greatest Moments, which will feature interviews with a host of Six, and Five, Nations legends, including contributions from players on the 1990 Grand Slam decider. It should be smashing.

England captain Will Carling: "As an Englishman, it took me time to understand the passion and depth of emotion the Scots have when they play England. Part of of our learning process was understanding, learning and respecting that, then making sure we felt exactly the same way about playing for England."

Joyous scenes in the Scotland dressing room, especially so as it's forwards coach Jim Telfer's 50th birthday. Stanger gets some orange squash poured over his head, Cronin tucks into a Mars Bar, and there ends the video coverage...

So, against all odds, it's Scotland's Five Nations, Grand Slam, Triple Crown and Calcutta Cup. Only Scotland's third Grand Slam in all, after wins in 1925 and 1984. The Murrayfield pitch is swamped, these are remarkable scenes. "We were written off by everybody," says Scotland skipper Sole, "but it's the year of the underdogs."

It's Underwood against the Scots at the moment but the hosts have him covered from all angles. England go left, Teague with the pick-up, Winterbottom to Hill, but Scotland snuff out the attack again. England with a scrum five metres out... penalty now, Scotland penalised for collapsing... England have to tap and go... Rendall goes, Probyn held, Hill finally gets it away, carling taking down by Jeffrey... AND THAT'S THAT, SCOTLAND HAVE WON IT!

... Underwood almost through again but Tukalo grabs an ankle and England are penalised. That should be that. A few hands on English heads now, they look like they know the game is up and they're about to be sent homeward, tae think again...

It's getting desperate out there now and England are reduced to running it from their own 22. Hodgkinson, of all people, with a bit of devil but Underwood is scragged. Here's Underwood again, trying to blast an opening down the blind-side... Carling now, breaking two tackles, to Hodgkinson, to Bailey, who is pulled into touch by Stanger... a minute to go...

England scrum on the Scotland 22... training ground move ends with Bailey being hauled down and Scotland are still not budging an inch in defence. Armstrong pinches the ball, Calder adds his grunt to the mix, before the terrier-like Jed Forest scrum-half sends a kick into England territory...

Cheer up Matthew, that's all over now.

Hodgkinson with another penalty attempt... he's hoicked it left. And they say booing kickers is a modern phenomenon...

England go right and Underwood looks like he might outstrip the Scottish cover... great tackle by Scott Hastings and it forces the loose pass. Gavin Hastings finds touch again, this time with his left, he's like a colossal boulder blocking the door to the Scotland fortress.

BBC One Former England captain Bill Beaumont

"One thing about modern international players is they're honed to fitness these days - they're far fitter than guys were in my day." (That was a decade before - Bill led England to the 1980 Grand Slam).

Scott to Gavin Hastings over on the left and that's a great cover tackle by Richard Hill, priceless work. A converted try for England would level the scores but it's starting to look less and less likely as we enter the last 10 minutes. England line-out on the Scotland 22...

England winning the battle for territory but they're not creating much in the way of try-scoring opportunities - ring any bells? Hill's pass is awry and Andrew is forced to kick to touch, although it's another beauty. Hastings clears and Hodgkinson's feet are in touch when he fields the ball...

Hodgkinson with another penalty and if he kicks this it will be a new English record for the Five Nations... pushes it wide. Off goes Guscott, on comes the 29-year-old Mark Bailey of Wasps, winning only his fifth cap in six years.

Rob Andrew has put Scotland in all sorts of trouble with a huge drop-out clearance but Hastings manages to clear again. Bit of handbags again between the forwards before Lineen gets up a head of steam in midfield. Armstrong grubbers, Hodgkinson with a decent return. Guscott still looking iffy after that knock, he might not be long for this game...
