"It started out with Eric Clapton and I just hanging out and kicking around some ideas and telling stories, playing a little bit of guitar and writing a little tune together," Robertson told Spinner.com. "We didn't have any particular purpose in mind, it's just that we'd known each other for a long time and that's what we do. We didn't really think about it much – we were off doing other stuff – and then I came back to it by accident a couple years later. I heard the stuff again and realized, 'Wow, we dug deeper than what I thought. Some of this sounds like the beginnings of something special.'"
