Do performers from non-US countries also vary up their national anthem with their own interpretation?

I can only speak for US and Canada, but I always thought it was odd how American performers often ham up the national anthem with their own "flavors" to the point where it's about them and not paying respect.

I just remember watching and feeling disgusted at Fergie making love to the US anthem, not because it was bad (I mean it WAS) but because it seemed so preposterously narcissistic.

To be fair, Canadian artists also sometimes do this, but it's usually shat upon when they do.

So how are national anthems treated in other places? I don't see the flowery renditions working in collectivist societies like in Asia, but I'm also curious about the prevailing attitude on other continents.
