No need for that, as I get VERY upset with the fact that many CHRISTIAN sources show rearranged and missing or added verses to songs that are 'old standards'.
Oh, I don’t know so much about that, I kinda like Chris Tomlin’s chorus addition to “amazing grace”.
But if you are adding/deleting major doctrinal points, that is another story.
First thing I do when I go to a new church, is check out the hymnal. It is usually the best gauge of beliefs/emphasis.
