Glen Campbell, who announced in 2011 that he was battling Alzheimer's disease, has been very vocal about his struggles with his progressive dementia. For that reason, the singer, along with his supportive family, will be honored with the inaugural Glen Campbell Courage Award at this year's A Night at Sardi's event, held in Beverly Hills, Calif. on March 26.

A Night at Sardi's, now in its 22nd year, benefits the Alzheimer's Association, and includes a celebrity musical revue and dinner. Jimmy Webb -- who wrote some of Campbell's biggest hits, including 'Wichita Lineman' and 'Galveston' -- will perform several of Campbell's songs during the show. In addition to Webb, the evening will also include a musical revue of some of Broadway's most memorable tunes from award-winning musicals, including 'Gyspy' and 'Funny Girl.'

Campbell, whose last album, 'See You There' was released in 2013, has been very public about his battle with the debilitating disease.

“I just take it as it comes,” he explains. “I know that I have a problem with that, but it doesn’t bother me. If you’re going to have it handed to you, you have got to take it, anyway. So that is the way I look at it.”

His family, including wife Kim and daughter Ashley, who toured with her father, admit daily life is becoming harder and harder for the 77-year-old.

“One time, he couldn’t use the television remote,” Kim recalls. “He knew what it was but couldn’t figure out how to use it. And he got so agitated that he threw the remote at the television.”

“It’s heartbreaking to see this disease robbing him of what he does best,” Ashley adds.

Campbell and his daughter have been outspoken advocates of finding a cure for Alzheimer's, even traveling together to Washington, D.C. to speak to US Senators.

“A person’s life is comprised of memories, and that’s exactly what this disease takes away from you -- like a memory of my dad taking me fishing in Flagstaff when I was a little girl or playing banjo with my dad while he plays guitar,” his daughter testified. “Now when I play banjo with my dad, it’s getting harder for him to follow along -- and it’s getting harder for him to recall my name. It’s hard to come to the realization that some day my dad might look at me and I will be absolutely nothing to him.”

A Night at Sardi's will be held at the Beverly Hilton Hotel. Tickets begin at $500 and are available for purchase here.
