By the time I got writing 'Halcyon,' I was on a roll, and I realized I had so much to write about, I realized I had so much built up inside that I couldn't really alleviate before, and then all of a sudden it was like reservoir burst.

I'm a bit of a like girly-girl, really, I like flowery stuff.

If I've got Writer's Block it generally means that I don't have that much to say or something's not quite connecting. I have had Writer's Block a bunch of times and it's generally because I'm not able to write down what I'm feeling basically. Mostly, I just need to be alone really, or be with someone who can bring that out of me.

The very first song I wrote was about a boy that I was obsessed with.

I started getting these attacks in 2009, just as my music career was taking off. I'd be doing photo-shoots and started to feel like I was having heart attacks. Increasingly I found it difficult to step outside my flat. Things started to get better after I saw a therapist, who told me I needed to make peace with my panic attacks.

Mumford & Sons' music appeals to a lot of America. I'm really proud of them.

I played recorder in assembly, then I became passionate about the guitar, I don't know why. I started on electric then moved to acoustic - my brother was playing bass in the next room.
