Sam Johnson says trying to hit the right note with his Scotland initiation was more daunting than making his Test debut against Italy.

The Glasgow centre was on song for Gregor Townsend’s Dark Blues as he won his first cap during Saturday’s 33-20 triumph at Murrayfield.

Australia-born Johnson — who qualifies through residency rules following four years at Scotstoun — put in an assured display as he took the step up to the international game in his stride.

The 25-year-old was cheered on by his parents, sister and niece after they jetted in from Queensland to catch his big moment.

Johnson admits he may have struggled to keep his nerves in check had he been thrown in front of the sold-out 67,000 crowd that cheered Townsend’s team onto a bonus-point win in their Six Nations opener when he first stepped off the plane from Down Under back in 2015.

But he never missed a beat, confessing his only concern was making sure he did not hit a bum note when standing up to sing in front of his teammates after the match.

“I’m pretty happy,” he said. “The opportunity has finally arrived and it was a privilege to finally run out there in front of everyone and sing the national anthem.

“I was more nervous about singing the karaoke after the match. I was definitely sweating about that. It’s a bit of an initiation ritual but it should be fun.

“As for the game, getting an early touch always helps you settle into the game and to express yourself.

“That’s the first cap out the way, now we’ll go again this week and see what happens.

“Did I feel comfortable from the start? I think that’s probably an age thing. If it was me when I first came here I’d have been pooing my pants.

“But when you get older and a bit more experienced you try to take your opportunities in your stride, so that’s what I did.”
