Senator Ed Markey, who lost his mother to Alzheimer’s disease, was among the speakers at a screening this week of “Glen Campbell: I’ll Be Me,” a documentary about the singer’s battle with dementia. Diagnosed three years ago, the Rhinestone Cowboy set off on a farewell tour, and a film crew captured many of the memorable moments, not least of all the country legend performing his music, including hits like “Gentle on My Mind,” “Wichita Lineman,” and “Galveston.” (The final tour of 151 shows included two dates at the Wilbur Theatre in Boston.) Remarkably, even as he struggled with Alzheimer’s, Campbell didn’t lose his lovely voice or his ability to play guitar, though he did sometimes appear confused on stage. Joining Markey at the screening at the AMC Loews Boston Common were director James Keach, producers Trevor Albert and Kim Campbell - the singer’s wife - and two of Campbell’s children, Ashley and Shannon, who played a few of their father’s songs at a party afterward at Blu. Today, the 78-year-old Campbell is off the road and living in a full-time care facility.
