The lead see-sawed between the sides after Ireland’s early lead thanks to the boot of Johnny Sexton but his opposite number Finn Russell responded for Scotland to give the home side a lead before the game ebbed and flowed back into the Irish favour before the end of the first half.
Errors were frequent with the half-time statistics reading 8-4 in Scotland’s favour in the unwanted handling errors category, while Gregor Townsend’s side also conceded 11 turnovers to Ireland’s six.
BBC pundits Johnny Barclay and Martin Johnson struggled to sum up the opening 40 minutes – but enjoyed it nonetheless
"Chaos,” laughed World Cup winner Johnson, “I loved it. I like a bit of chaos – but it’s a difficult game to get your head round.”
"Bonkers,” said Barclay who added Scotland’s chin-assisted try “summed up the game, just bonkers – a comedy of errors”.
