It's a different thing when I sit down with [Memphis songwriter and longtime collaborator] Keith Sykes or some of my buddies in Nashville. It's more likely that I'll actually make the appointment and I'll have some fun and maybe at the end of the day we'll get a song out of it. But I've never had any discipline whatsoever. I just wait on a song like I was waiting for lightning to strike. And eventually -- usually sometime around 3 in the morning -- I'll have a good idea. By the time the sun comes up, hopefully, I'll have a decent song.
