I once had a brief serendipitous moment flash by me on stage. I was singing Down by the Glenside and in the middle of one of the later verses I suddenly realized--while sustaining that beat-and-a-half note in the middle of a line--that I had just sung the wrong words. Then came the terrifying thought, Now what am I going to do? But by then the note was ending and I had to go on. I went on. Words came out of my mouth. They somehow made sense--matched what went before and also the rhythm and scanning of the music. I breathed an internal sigh of relief, picked up the normal words in the next line and went on to finish the song and the concert before I thought about it again. And danged if I couldn't remember what I sang. I'm not even sure it really did make as much sense as I thought at the time--like those "great ideas" we sometimes have in dreams. But it sure was an amazing feeling to be carried by some unseen force for those few moments.
