Rick's point is soooo good. Being the master musician he is that lost chord is VITAL. I so understand. I think the point about the conciseness of lyric is a basic one. The art of the song lyric is the art of saying the most in the least, and my experience shows me that most people add redundant words to lyrics and it offends mine ear! In speech now in England everybody is adding redundant "up"s to everything and it drives me potty. "fess up" ie confess.(hang on, this is another thread!)
