I suppose it's unnecessary, but "dirty word" was a metaphorical phrase; in no circumstance did I mean to imply that anyone as far as I know actually think that "kumbaya" is a nasty word. If anyone got that impression, mea culpa for not making myself clear.

So do all the truly great and thoughtful responses to "Kumbaya" as a song and a concept also then apply to The Times They Are a'Changing and Blowin' In The Wind (as well as some of the other naively hopeful songs already mentioned like Last Night I had the Strangest Dream, etc.)? (tough to handle punctuation in a parenthetical).

They must. What were we thinking back then, then? And what has changed in us?
