It sounds like I'm joking when I say it, but when I wrote 'Take Me To Church' and a lot of these things, I didn't think they would be hits. I thought I was writing for a potentially smaller audience.
If I don't think something's worth saying, I don't think it's quite there, I'd rather just not say it, to be honest. In that case, I'd rather wait 'till the thought is ready, 'till I feel like I'm happy with everything.
I'm influenced a lot by Nina Simone, Stevie Wonder, even Paul Weller - Billie Holiday as well: People who wrote and sang songs that were reflective of their times. I quite like that. I quite admire that.
It was amazing for me to even perform at the Grammys, but to do so alongside Annie Lennox was a truly incredible honor.
There are a few Irish writers who have a very strong influence on me, especially on the 'Take Me to Church' EP.
I have a bit of a love affair with fairy tales and some of the ideas of Irish mythology, like Oscar Wilde and W.B. Yeats, who captured a lot of that very beautifully.
Growing up in Ireland, there are a lot of aspects of God that hang in the air. And my music reflects that.
I found the experience of falling in love or being in love was a death: a death of everything. You kind of watch yourself die in a wonderful way, and you experience for the briefest moment - if you see yourself for a moment through their eyes - everything you believed about yourself gone. In a death-and-rebirth sense.
One of my first festivals was Oxygen 2006. It had this amazing lineup with the Arctic Monkeys on their first or second album, the Strokes, Kings of Leon, the Magic Numbers and then the Who and James Brown. I waited in the pit for a good eight hours to see James Brown.
Either somebody has equal rights, or they don't. And certainly in the Irish constitution, marriage is genderless. There's no mention of a man and a woman.
I think it's very hard to write things about being joyful. I find that quite difficult. I think when you're happy, you don't want to write songs; you just want to enjoy being happy.
I love making music, but if you make something that inspires somebody else to make something, without getting too airy-fairy, you've contributed to the zeitgeist in some way, and that's just an amazing feeling.
