There's a quote from it in the book
Wouldn't It Be Nice If It Were My Own Story. If you don't own a copy, your library probably has it....I don't know how
accurate it is, though, but it's in there.
Or...a quick Yahoo! search turns up this text:
What kept me going is the same things that got me to write "Surfin'" all those years ago. I wanted to write joyful music that made other people feel good. Music that helps and heels, because I believe that music is God's voice.
That's not the
whole thing, but that's the big "God's voice" portion.
