Last night I saw "Glen Campbell: I'll be me" (2014) on Netflix. I was never a big fan of Glen Campbell, but I was deeply moved by this film.
IMBD: "In 2011, when Campbell was diagnosed with Alzheimer's disease, he joined forces with his family to fight the biggest battle of his life. Glen and his wife, Kim, made history by going public with the diagnosis - the first time a major American celebrity would share this experience with the world. The Campbell family then embarked on a short "Goodbye Tour," but the three-week engagement turned into an emotional and triumphant 151-show nationwide tour de force."
The movie tells the story of this tour. If you haven't seen it already and you have the chance to see it, go for it. Great movie and to my surprise, great music too!
