I was just 20 years old when I wrote Broken Arrow.

I wanted a participation song, something the fans could latch on to. It was aimed at the masses. I wanted to write something that everyone could sing along to, like a football chant. And at the same time, I thought it would be nice to have a winning song that's meant for everybody. It worked a treat.

A song is like a dream, and you have to make it come true. They're like strange countries that you have to enter. You can write a song anywhere, in a railroad compartment, on a boat, on horseback -- it helps to be moving. Sometimes people who have the greatest talent for writing songs never write any because they are not moving.

I used to write random little stupid things when I was five, but then the first song I really wrote was one called 'Fingers Crossed,' which is on SoundCloud.

I kept talking to my producers at Columbia about recording one of those [prison] shows. So we went into Folsom on February 11, 1968, and recorded a show live.

Every week, Dennis Day sang an old Irish folk song. And next day in the fields, I'd be singing that song if I was working in the fields.
