i think t might be something similiar to what happen with something for the pain, they had the song ready, but didn't like it, so they change it all, the chorus are now the rest of the lyrics(sorry i don't know the name), and those lyrics are the chorus, may be that happen with bitter wine, but they also had to change some lines, and the cd book that ready when they change it, because we have to remember these days came out very late, they did cross road because they didn't have ready de songs for a new album.
i hope i explained it well, sorry for my english
