This is an original song, titled 'Call Me Crazy'.

"I'm headed into harms way. That's where I'll be headed until my dying day.
It's what you do to me. Call it crazy. Call it crazy.
I've been searching, for something true. And I'll keep searching, although I've already found you.
It's what you do to me. Call me crazy. Call me crazy.
Am I searching for something that can not be found?
I hear what they say about the second time 'round.

It's okay baby, we were fine from the start: Everything except all those crazy parts.

It's what you do to me. Call me crazy. I'm just crazy. "

Repeat chorus

This.Is.My.Favourite.Wall.

You can do that: have a favourite wall. 

You can have a favourite anything as far as I'm concerned.
