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

Then, you know, the other more-traditional role of the producer in, like, the kind of Quincy Jones sense is kind of part arranger. So you're coming up with, like, these - you hear these songs that are quite bare-bones, and you dream up what's the band doing? What's the rhythm section doing? What's the guitars, strings, pianos - that sort of thing. It's almost like a little toolbox.

I mean, my wife is always like - I don't write lyrics. So I couldn't, like, really technically write a song for anyone. I could write a very nice instrumental. So she always sort of gives me a hard time because it's just such a ridiculously impossible standard to live up to, that your step-dad wrote that song for your mom.

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.

And sometimes, I'd be allowed to be hanging out in the studio, which I just loved kind of, like, being in the room with these big recording desks, with all these, like, buttons and knobs and watching the guys use them.

I never studied jazz technically; I just know and love the music.

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.
