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.

I could go play some songs for two hours every week - play whatever I wanted to - and then also spend that time putting more music on my computer and getting into more things. It definitely informs the way that I think about music and I think in general, made me a more open-minded consumer of music.

I remember being like, 12 years old, and this was in the days before cell phones, or at least, having a cell phone. Some girls, I can't even remember who they said they were, called and said they had a crush on me. But it turned out to be a prank, and I thought that was just straight up nasty, you know what I'm saying? You're just sort of developing. You're insecure, your bones are growing... you have trouble sleeping. And all of a sudden, someone's pranking you on top of that? It's tough growing up.

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 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.

I didn't get any college credit for playing in Vampire Weekend, you know. So it was definitely an early hurdle to get over with C.T. winning and us losing to C.T.. But I think sorta since then, in the four years since, we've managed to pave everything over.
