That was beautifully done.
It took me a while to find it again. I think that's the third time I posted this. It's a haunting melody. I think its nearest counterpart is Amazing Grace however it is performed. The most amazing renditions were in the Madrid underground and Gare du Nord where a string quartet was playing.
It is a mystery how deeply most people are moved when listening to Amazing Grace -such power from a simple, unadorned song. I've never had the pleasure of hearing a live professional rendition of Amazing Grace.
