I first heard this in Canada, somewhere in rural Ontario. We were there on vacation, and the local CBC station played this as we drove. My brother and I were thrilled; my parents were not but did not say anything. What impressed  me then was the length and the story line.

This epic was released almost a half-century ago: 20 July 1965. Recently the original lyrics sold for $2 million.
