In 2011, country legend Glen Campbell was diagnosed with Alzheimer's disease, and faced with such news, many other artists might have chosen to stay away from the public. But not Campbell. 

The "Rhinestone Cowboy" decided to hit the road once again and performed more than 150 shows before his final appearance in Napa two years ago.

The new documentary "Glen Campbell: I'll Be Me," directed by James Keach, looks at Campbell's battle with the disease and how it affected his family.

Director James Keach and Glen Campbell's daughter Ashley, who is also a musician and played with her dad and siblings on the tour, joined Take Two to discuss the documentary.

"I'll Be Me" is currently playing in the L.A. area at the Laemmle Music Hall and Burbank Town Center.
