.... and the end the classic blow-off, minor emotional peak.....

There is something about some performances of a song that I can come to call last verse syndrome. A song has been going well; no slips - no forgotten words - no stumbles. You can feel that sense of relief, particularly with inexperienced singers, towards the end of a song and there is a lapse in concentration, a switch off just too soon and that is when the words don't come out or there is a drift off tune or some other slip up.
