Dr. Ralph Stanley has blessed us with his presence

Dr. Ralph Stanley is the FATHER of mountain/bluegrass music, and Thanks to F. Warren Hellman we (San Franciscans) have been exposed to one of the greatest, let me reiterate, THE GREATEST, musicians of all time.
FOR FREE.
Thank you Mr F. Warren Hellman for a pleasant surprise. Please Please have the Bluegrass festival again next year and Please, Please invite Dr. Ralph Stanley (Before he passes).
We all need to hear and see him perform at least once in our lives.
I cannot stress enough what a privilege it is to see and hear the Father of Bluegrass/mountain music right here in SF.
