I know I rag on about GL a lot..but he is one of my favorite, if not THE favorite singer songwriter.  Now this is from a brief interview in 1970 by 2 guys from the newspaper Georgia Strait (based in Vancouver); I think it is still published.   The interview is actually quite funny in parts, especially when Lightfoot describes the ordeals of certain interviews, and his nightmarish experience on a TV broadcast.   The fart into the microphone is a classic...what a human touch; wonder if they saved it on tape!
