No, Frogprince, "unfoolish" is correct. "I'm foolish" makes no sense there. Think about it: He wants to meet the girl in the bar, is trying to figure out how to approach her, what he can say, and doesn't want to say something foolish--it's a great image, as one knows who has spent his time in bars looking from bottle to bottle and who never had a "line." Besides, I used to have the song book which accompanied the album, which I still have.
