I've watched it tonight, the documentary before the concert, I always feel quite emotionally attached to him for some reason, only shuck his hand but he was so humble and charming, kept it together 'til Jimmy Webb told how a year or so ago he was with him and glen turned to Jimmy and said 'did you write Wichita lineman?' broke my heart that bit, so sad.
I was enthralled by his life story and I also watched him in concert afterwards. He had such charisma, and was an accomplished guitar player. A quiet gentle man , I remember him while I was growing up, but did not know any thing much about him. I wish him all the best.
