I think it's perfect, but it's not even in the lyrics of the original version, it's just in the title.

However, I'm pretty sure I saw Bob add a 4rth verse to the song one time in a live concert and he added the words of the title in that verse much the same as I did...thus you get a fourth verse that kind of wraps up the whole thing neatly at the end.

So that's the way I do the song now.
