(audience applause) - So one of the first songs we wrote together is this next song that we're gonna play.

And we were about three weeks out from making the record and we hadn't written anything yet... 'cause we are overachievers.

(audience laughs) So we started scramping and you know, like sending voice memos and ideas and melodies and stuff.

Martin started sending over lines about how, I'm not gonna do this if you don't do that.

And I'm not going there if you're not gonna do that.

And Kimbro and I were quite convinced he was just sending us things that his children were saying.

(audience laughs) But it turned into a really sweet song that we'd love to play for you right now.
