Well - that's very interesting and it's the first time I remember there being any evidence of Don altering the lyric. Maybe it was a one-time mishap or perhaps the band has targeted certain markets or cities (probably in the Bible Belt) where they have decided to alter it.
BTW - I am going to do as suggested and create a new thread for the discussion about the use of profanity in their songs. Feel free to post here until I set up the new thread and I'll move all the posts over.
