Scotland returned to a major tournament for the first time in more than 20 years when they booked their place at Euro 2020, and the Tartan Army quickly adopted an unofficial anthem.
When David Marshall saved Aleksandar Mitrovic's penalty to pave the path to the European Championship, a nation erupted in a chorus of 'Yes Sir, I Can Boogie'.
Marshall himself earned his own tribute song, but Baccara's 1977 disco hit is the one that will feature most prominently at Hampden Park and further afield in the years to come.
So, in case you're brushing up on your lyrics or you're wondering what it's all about, GOAL brings you all the details of Scotland's new unofficial anthem
Yes Sir, I Can Boogie lyrics
Mister
Your eyes are full of hesitation
Sure makes me wonder
If you know what you're looking for
Umm, baby
I wan't to keep my reputation
I'm a sensation
You try me once you'll beg for more
Ooooh!
Yes sir, I can boogie
But I need a certain song
I can boogie, boogie-boogie* all night long!
Yes sir, I can boogie If you stay, you can't go wrong
I can boogie, boogie-boogie all night long!
No sir,
I don't feel very much like talking
No neither walking
You wanna know if I can dance...
Yes sir,
Already told you in the first verse
And in the chorus
But I will give you one more chance...
Ooooh!
Yes sir, I can boogie
But I need a certain song
I can boogie, boogie-boogie all night long!
Yes sir, I can boogie If you stay, you can't go wrong
I can boogie, boogie-boogie all night long!
Ooooh!
Yes sir, I can boogie
But I need a certain song
I can boogie, boogie-boogie all night long!
Yes sir, I can boogie If you stay, you can't go wrong
I can boogie, boogie-boogie all night long!
Ooooh!
Yes sir, I can boogie
But I need a certain song
I can boogie, boogie-boogie all night long!
Yes sir, I can boogie If you stay, you can't go wrong
I can boogie, boogie-boogie all night long!
Ooooh!
Yes sir, I can boogie
But I need a certain song
I can boogie, boogie-boogie all night long!
Yes sir, I can boogie If you stay, you can't go wrong
I can boogie, boogie-boogie all night long!
*sometimes sung 'boogie-woogie'

Why do Scotland fans sing 'Yes Sir, I Can Boogie'?
The adoption of 'Yes Sir, I Can Boogie' by originally came as a tribute to Aberdeen defender Andrew Considine after he took part in a joke video of the song on his stag party.
Considine was part of the Scotland squad that qualified for Euro 2020 and the song quickly became a dressing room hit before a video of the players celebrating to it went viral.
The Dons icon was in the thick of the singing and dancing, alongside Scott McTominay, Andrew Robertson and Kieran Tierney. Unfortunately, John McGinn and Ryan Christie missed "the boogie" in order to undergo a UEFA-mandated drug test.
Fans have embraced the catchy number and the official Scotland social media channels have even promoted a Spotify playlist featuring the song for supporters ahead of games.
