I thought i would share my experience with this community because I know many people will appreciate this. I am currently writing my thesis at a rehabilitation facility for individuals with traumatic brain injury in Colorado. For my thesis I have written a program to assist a man with amnesia (on good days he remembers his sons names), he really has very limited memory.As I learned more about him, I found out that he was a crazy Dead Head. So, between trials I give him breaks where we just listen to Dead tunes. To my amazement one day he busted out singing all the words to Ripple. It was mind blowing to the point it gave me goosebumps and it brought to tears. What was even more remarkable, is that his accident also left him with impaired speech, but I was able to understand exactly what he was singing, and he was able to sing in sync with Jerry. A feel privileged to have witnessed it.It just shows you the power of music. Happy B-Day CH
