Stuff just comes out all the time, sometimes when I sing live it really comes alive and I sort of... I write songs and then almost... not forget about it, but live it really comes out and I suddenly realise what I've written. I don't know where it all comes from.

I wrote 'Lights' a long, long time ago. And I expected it to be on the album, because it was - I wrote it with 'Biff' Stannard. And he wrote every single Spice Girls song and every single pop song of the 90s, basically. So I thought, you know, I was really lucky to work with him, but I didn't think it would be a big song for some reason.

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.

It took time to really build myself a reputation as a good live performer, a musician and an artist.

I would like to be mates with Richard Branson because I've hung out with him and he is just the loveliest person and obviously a very rich guy and has a lot of stuff going on, but he's actually a really, really sound person, and he's really positive and he's got a really good energy, so I'd like to hang out with him a bit more.

Apparently I'm introspective... levelheaded... but at the same time, absolutely insane.

I think all the covers I do have nice sentiments, particularly 'Your Song.' People write me very sweet messages about that song, though I'm sure there are people out there saying that I've ruined it too!
