The astonishing scenes in Cardiff when Wales played Ireland for the Grand Slam in 2005

Saturday's Six Nations Grand Slam decider against Ireland will be some occasion for every rugby fan in Wales.

It will also rekindle memories of arguably the greatest day in recent Welsh rugby history.

Back in 2005, the Irish were in town again with history on the line. It was a remarkable time to be Welsh as an astonishing day unfolded in Cardiff after 27 years without a Grand Slam.

It hardly seemed possible so many rugby fans could fit into the Welsh capital with City Hall, Westgate Street and St Mary Street packed to the rafters... and we were still hours away from kick-off.

An estimated 250,000 supporters made Cardiff their Mecca that day... it could have been double that, but who was counting?

Even the weather Gods looked down on Wales as the city basked in Mediterranean temperatures and the team bus bringing Mike Ruddock’s gladiators into the Millennium Stadium amphitheatre almost ground to a standstill amid chaotic scenes as thousands of red-jersey, daffodil and leek holding fans packed the route 10-deep to get a glimpse of their heroes.

Players were visibly lifted by the scenes entering Cardiff, and inside the stadium those lucky enough to get hold of a ticket (they were literally like gold dust) were treated to a rousing pre-match sing-along from Max Boyce. The pride of Glynneath was joined by Charlotte Church and Katherine Jenkins for an emotional roof-lifting rendition of Hen Wlad fy Nhadau.

The match itself was unbelievably tense, but Wales survived some anxious moments to claim their first Grand Slam since 1978 with a 32-20 victory.

Cue wild celebrations inside the stadium and out with the most rousing version of Delilah ever heard in the Cardiff citadel as Welsh players paraded the trophy.
