Scottish fans booed Liechtenstein’s national anthem because it has the same tune as God Save the Queen, which they understand to be England’s national anthem.
The Scottish Football Association has apologised for the embarrassment, but strangely didn’t apologise to their own fans for the embarrassment of only beating Liechtenstein (pop. 36,000) by only one goal.
I’m English and I was at Hampden that night with a Scottish friend. I knew the Liechtenstein national anthem had the same tune as God save the Queen. I’m a staunch anti-monarchist and had to have a little chuckle to myself at all these Scots getting themselves worked up over a piece of music.
