Scotland fans belted out the national anthem with incredible passion prior to the friendly with England on Tuesday evening.
The two nations face one another at a sold-out Hampden Park to mark the 150 anniversary of their iconic rivalry.
It was the first encounter in Glasgow since a dramatic 2-2 draw back in 2017 and when the national anthems played out pre-match, the Tartan Army did not disappoint.
Flower Of Scotland, created by Roy Williamson and adopted by the team since 1997, was sung by 50,000 Scots, who created a quite deafening noise inside the stadium.

A clip was posted online by beiN Sports and the expressions on the faces on Scotland fans was a picture.
England players sang 'God Save The King', the anthem for the United Kingdom, but it was drowned out by a loud chorus of boos from the home fans.
The last time the two sides met was at Euro 2020 when they played out a dismal 0-0 draw in the group stages.

Together they are responsible for the oldest ever international fixture and one which ultimately led to England wearing white.
Scotland were wearing full navy kit as their side, made up entirely of Queenās Park players, sported their club colours.
England had to wear something different to ensure there was no clash and according to a report from the Sun, he FA supplied white kits, which may well have been spare cricket tops.

At one stage, players would wear white-collared shirts but teaming them with their club shorts and socks before navy shorts and white socks became the classic combination we see the Three Lions wear today.
The fixture in question was played at West of Scotland Cricket Club back in 1872 in front of 4,000 fans and finished without any goals for either side.
