Wow. Shows what an ignoramus I can be, with all my hifalutin eddycation...

"Four dead in Ohio" I heard as "forgetting Ohio"

What if you knew her and found her dead on the ground" I heard as "...and found her head on the ground"

In both cases the gestalt I got was that this was an anti-Vietnam War song, about some kid from Ohio who's seeing such atrocites, fellow soldiers killed and all he finds are some random body parts that he can recognize (and hey, I thought that this meant they had women fighting in the trenches, which I thought was a great thing for women's lib) that he forgets about his home town, like forgetting that it even exists, let alone hoping he'll make it back there someday. Still a stirring song of protest, but not against what I thought it was! See, the Mudcat can eddycate, too! I shall have to find a recording of this and listen to it all over again.
