I'm not one of those players who always gets to games or watches every game on TV. If a game is on and I'm free, I'll watch it but I won't make my schedule around a football match.
As a very patriotic and passionate Scot, singing the anthem at a big football match means the world to me and I'm so lucky and so honoured that I get asked to do this.
I met Jack Bruce, one of my heroes, in a studio while doing some recording. England had just beat Scotland in a big football match and I saw Jack trying to break into this refrigerator in the lounge, drunk out of his brain, and I didn't know what to say.
The first ninety minutes of a football match are the most important.
I'd 1,000 times rather go see an NBA game than a football match.
I've played in a few Champions League matches and got into quarter-finals - sometimes unluckily knocked out - but you have to prepare like any other football match: you have to play the game, not the occasion. That's been instilled in me since I was a kid.
You gain know-how from playing matches because every moment of a football match has its own rhythm.
To see my country lose a football match is very hard for someone who has worn the shirt.

I attended the bedside of a friend who was dying in a Dublin hospital. She lived her last hours in a public ward with a television blaring out a football match, all but drowning our final conversation.
