Basically, there's a good friend of mine who works at EMI Publishing, a publishing company. He had asked me - he was like, you know, do you know this girl, Amy Winehouse? She's in New York for a day. She's kind of meeting people to maybe work with on her second album.

So when I was working with Amy Winehouse on "Back To Black," you know, she had all these beautiful songs, incredibly well-written and just her on an acoustic, nylon-string guitar. And she'd play them for me, and then I would kind of drum up my idea of what I thought - make a demo with what I thought the drums should be doing, the guitars - like, quite a crude demo.

I don't have a crazy rider clause saying I have to stay at fancy hotels. I don't have a problem with staying at a Marriott. But I will admit that I've gotten just basic, regular service there.

You know, like, there's songs like "Valerie" and "Bang Bang Bang" that I was so proud of. And, you know, the level of success that they had - if they were little cult hits meant that, you know, I could sellout Webster Hall or Williamsburg Musical Hall or the El Rey theater in LA. Like, that was having made it to me. So the thought of having a number one song in my own career, like, never even registered.

I think Katy B encapsulates young London in a way I never could. She reps London harder than anyone song-wise since Lily Allen.

I think that that spirit, or at least the raucousness of maybe that, is in there. And then yeah, like, along the way, you fine tune it 'cause you're thinking, like, OK, we need to now turn this into a song.
