This is an extremely extended version of the story, which focuses just as much on Stag's "sweet-lovin' wench" as on the bad man himself. (In fact, Stag dies before the second half of the record even starts! We don't even get to hear about his adventures in hell.) It's also interesting that Edwards is from St. Louis (Missouri), the city where the real-life shooting took place, just six months after Edwards was born.
(This record hasn't been reissued since 1975, except a very rare CD in Japan, so the buy link is wishful thinking, really.)
