I grew up on the Kingston Trio version, but rapidly grew tired of the oversweet, drain every tear covers by PP&M, the Journeymen, Brothers Four, etc. I thought that was all that was out there, and I was just throwing this into the collection for sake of completeness.
When I listened to the different versions I found I liked Roseanne Cash's lush and heavily backed interpretation and Hedy West's arrestingly simple one. I eventually chose this one, even though it's a bit uncomfortable and stretches the song's meaning. There's something compelling about it. And it's got great trains.
