Q. You were at a Jason Derulo concert?

"Well, I'm a big fan."

Q. So is this you then? (Shows Martinez the mobile phone footage.)

"Is he moving well or not?"

Q. You tell me.

"Oh yes, that's a big, smart car, yes."

Q. So it's you, yes?

"Yes, it is."

Q. I was hoping it wasn't.

"Why? It's always good to get some inspiration from creative people."

"Yes, very good."

Q. That's the problem with these phones, isn't it?
