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.

I'm not really much of a prankster, but I've definitely been pranked. I never really liked being pranked, so I generally try not to prank people.

Now, I'm mostly a beer man. When I drink hard liquor, it usually doesn't end the best, so I keep it chill with beer.

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.

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.

There's still people that do it poorly... and people that do it very, very well. I think there's still an incredible spectrum. I guess there's something that's appealing in it, in that everyone on some level is a DJ. But people still go to clubs, and there's still... it is interesting - with everyone having an iPod now - when music is so personalised and things like Pandora and making your own playlists, there's something really powerful about a room full of people all dancing to the same song.

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.
