I believe this is a live recording from San Quentin and JC gives a little introduction about how he came to know the song -- "There's a young man here at San Quentin tonight that wrote a song..."
What followed flabbergasted me; "He sent me the sheet music on it and I don't know anybody that reads music...I liked the lyrics so much I started singing my own tune to it..."
Taking JC's comments at face value, neither he nor members of his band read music. I know there's plenty of stories out there about musicians and their lack of formal training, little music theory knowledge, etc. But for me, this admission was eye opening. I would have expected someone in the band or someone associated with it to have music reading skills...

"It takes a lot of devotion and work, or maybe I should say play, because if you love it, that's what it amounts to. I haven't found any shortcuts, and I've been looking for a long time."
