Sam,

Listen to the singers when the harmony is just right. There is another voice that is heard that isn't made by any one singer but it is there none the less. This ghost voice is there when the storyteller has you the ears and though your eyes are open, you see the words of the story in pictures before you. The ghost is there too when when the whistle and the harp recall O'Carolan from the grave and their blended elegance melts your heart.

You are correct, there is a second level at which performers may play, no one ever all the time. But some more than others and I am happy when I reach it now and again.

Regards

Don
