I have discovered that I can be looking right at the words - directly from the DT or wherever - and not sing what is written. This is not a new thing with me so I can't really write it off as symptomatic of my advancing age. I have no idea if it is because an alien suddenly takes over my body or what. All I know is that the words coming out of my mouth are usually recognizably similar to the written lyrics - but not quite the same. This doesn't always happen, but when it does, the "new" words always seem to make sense. So, for the most part, it doesn't bother me. But it sure irritates the hell out of whoever is trying to sing along with me! Maybe the forces within me want to hasten the folk process a bit. Or maybe it is just brain creep.
