It was more just about serving the song, which is sort of the way that we work in general. We wanna do the best that we can with it and make it the most interesting to our ears. And putting auto-tune on 'California English', was just one reflection of that.

When you're a music director, you have people constantly sending you music and trying to get - I mean, I'm sure you have the exact same thing when you do a magazine - that you have people constantly wanting to get your attention. And I think I learnt a lot from being on that end of things, when I was trying to book the tour, the first tour we did.

There were people I knew that came to college and had never drank before, and never partied, and maybe got a little bit too carried away with it when they did finally get out of the house... I feel like I got that stuff out of my system when I was sixteen and knew to balance things - but at the same time - it's not like I was out getting my medical degree. Playing in a band, you can still have plenty of fun!

I did it a little bit in college, but now I've been doing it more. But yeah, it's not, I think you can definitely have a sense of humour about it. Like a lot of the time I'll finish my set with 'Sandstorm' by Darude - do you know that song? That's a funny song. People also go apeshit when you play it. But at the same time, it's not like the whole thing is a joke.

Maybe it's just a humanising thing to realise that a ton of people in bands that make really exciting music, are just big nerds. And you know, maybe the Internet's done a lot in just exposing that long-held secret.

I think Justin Bieber played a couple of songs up the block from it - and they said that some-one in his camp came and got him a burger. We had been talking about him a lot. Especially actually, last time we came to Australia, C.T. was on a real big Justin Bieber kick. I just thought it was really interesting to finally cross paths with him in New Zealand. And like really - the TV, everyone's just talking about it on the radio - it's a big deal that he was here. I think he just left.

When you're working on a record, I find it's better not to share details during that process. Because, until it's done, it can change.
