We were on a tour, and there were some chord formations that were tough for me to play when I was a kid...it had become apparent that there was some stuff I wanted to do that [would require me] to learn how to do that. So I wrote the song and used some of these chord formations so I would have to play them. I thought it would be a great teaching vehicle for a while, and it was, but it ended up as a performance song.
