HM to "How Long," even if I don't quite know what "fancy persuasions" are.
I seem to recall reading that the song is not about a (love) relationship breaking up via unfaithfulness (as widely assumed) but that it was a member of the band castigating the others for something-or-other. So your guess about "fancy persuasions" is as good as anyone's.
You know, back inthe day I thought the was a song about a cheatin' lover, but after awhile that changed & for many years now I've assumed this to be about a backstage conspiracy, a la Brutus & Julius Caesar.
Oooh, BOS F Mac, a B-N twin-spin of sorts, right?
