Interesting site spaw, but it doesn't do anything to answer the question.

I'd have thought this is the kind of thing Dylanologists would have all the facts about at their finger tips. Maybe we haven't got any resident Dylanologists, which would seem surprising.

If anyone should say "sorry" it's me, Swan, because my post with thelink comes across as a bit snide, which it wasn't meant . But it's not a song I've ever thought of as being called Percy's Song, though I know that' what it says on the album, since the name never come into the lyrics.

I'm curious now.
