The former Ellon and Aberdeen Grammar flanker, now at Glasgow, took his bow as a 63rd-minute replacement for Ally Hogg during the surprise 38-7 win over the Baa-Baas at Pittodrie.
While it could be argued that the youthful Scots beat ageing opponents, they were also experienced rivals and a victory against any Baa-Baas side is no mean feat.
The achievement - Scotland's first win in 10 attempts against the Baa-Baas - can be measured by the fact it was accomplished without regular starters such as Chris Cusiter, Gordon Bulloch, Jason White and Simon Taylor.
But Andy is not getting carried away. He said: "Hopefully this will be the first of a lot more to come my way. That is not down to me, though. I just have to go out and do my job at club level.
"To produce a result like that without other important players such as Chris Cusiter shows we are building again."
Scotland's five-try haul under interim coach Frank Hadden set them on their way to burying the memory of Matt Williams's 17-month tenure.
Whether Andy is part of the side which lines up against Romania on June 5 ahead of the autumn Tests remains to be seen. He insists, though, this latest success must be used as a springboard towards a better future.
The 24-year-old said: "We cannot dwell on what we have done. We have to go to Romania and get a good result to keep progressing. A word we used before the Barbarians match was enthusiasm, and it was there in abundance.
"Everyone was eager to work for each other and that showed through, particularly in the second half.
"This is one step and, hopefully, many more will follow. The coaches are aware we still have a long way to go, as are the players. We are just happy with a victory and it is good to simply get on that first rung of the ladder."
For Andy, making his Scots debut in his hometown was a special moment after coming through the youth ranks at international level.
He admits he would love some more of the caps he is hoping for to come at Pittodrie, where 20,228 supporters turned up on Tuesday.
He added: "I was really chuffed to get on and it was brilliant to see the crowd being close to a capacity one.
"It just shows taking our games around the country is a good idea and the atmosphere was electric. I would love to see international games brought back up here again, although it is not up to me to make that happen.
"If it is meant to, though, it will happen in time and it would be good to keep producing crowds like the one we had this week. The demand is certainly there and it was fantastic to see so many people inside Pittodrie. It is great for the area."
