I guess if you do original songs, like we do often, it doesn't bother me. My P&W leader, who is releasing her first album this summer, write a lot of material. Actually, she came to mid week service with a tune in her head and we sang it that night less than an hour later. No one in the congregation new until the pastor got up and told the story of who his wife, P&W leader, was given the song by God. So, the band I'm with, we do and will change musical phrases within a song because its our original material. But before we do it, we make sure everyone is aware and on one accord, ie. communicate. I don't want anyone to get to feeling that I'm on the opposite side of the fence, but I'm opening my mind to see all sides.
