A new documentary about the life and career of music icon Glen Campbell opens in theaters today nationwide.

"I'll Be Me" is not an ordinary music biopic because Campbell was diagnosed with Alzheimer's disease in 2011 and decided to deal with it publicly. The film documents his emotional "Goodbye Tour" and how his wife Kim became his caregiver.

MPR's Cathy Wurzer spoke with Kim Campbell and Dr. Ronald Petersen, Director of the Mayo Alzheimer's Disease Research Center. He was one of Glen Campbell's doctors.

We've posted some video clips of Campbell, including the official trailer for the documentary.
