Had you been in touch with Beyoncé’s people for a while before you actually did the song?

Not for that long. She has very nice people working with her. To be honest, in that world of very, very high-profile musicians and artists, it's quite rare to have a personal touch, because by that point it's kind of a well-oiled machine and sometimes experiences like that can be quite sterile. I enjoy working with somebody that collaborates in the traditional sense, where you actually sit down and make music. I was worried a little bit that it wouldn’t be like that, but I was working with material that she'd made and collaborating with it. Getting to chat with her about it was really nice. I guess that's as good as it gets with somebody as brilliant as her. With somebody at that level, you can never really be sure, just because there's so many people involved in a record, but she's such an accomplished writer and singer.
