Do You Have a Core Idea for a Song?

In bands as far back as high school though weren't you so were you actually writing songs back then or is that something you arrived at a bit later. These days there's some writing very much at a solo pursuit for you are you open to a co-write here and there? I don't really know how to do it with somebody else there's a few times where I've tried but the core idea doesn't start with two people it always has to start with one brain, he says.
