Heck I heard the same things about John Prine after his surgeries.
I can listen to him all day and night.

Amazing isn't it. some of the great crooner with perfect tone, I can't take more than a song or two. Cause for me it is all about the emotion in the performance.

Our Jeri once said, "when you listen with your heart you tend to hear it with your heart".   

That is a beautiful saying Jeri cause that is what music to me is about.
