Toby Keith pays tribute to Glen Campbell during concert

For years, the dreaded disease of Alzheimer's had been destroying Campbell's memory, body and soul. Then, the following year, the 2014 documentary Glen Campbell: I'll Be Me - one of the best of its kind - documented his battle with Alzheimer's as he embarks on his farewell world tour and the pain his family endured dealing with his care.

When I first saw Glen Campbell's face, after he got his own TV variety show, I recall being struck by how he nearly looked like a kid. Daughter Ashley posted a poignant photo of her dad.

Veteran Broadway actress Barbara Cook, known for her prolific career in musicals and cabaret and her soprano vocals, died on Tuesday from respiratory failure, her representative said.

Dolly Parton said: "Glen Campbell was special because he was so gifted". "He was also one of the greatest musicians". Tim McGraw Tweeted: "Songs, songs, songs".

"That's what we grew up with - the good songs, the good lyrics, the good big-band stuff". Check out the country music maven's tribute to the late star here! "I'll forever love you, Glen". Kenny Rogers said:✔"So very sorry to hear this". I thought he was great in it, funny, courageous, a guy who could hold his own against John Wayne's formidable Roster Cogburn. Lee Greenwood said: "There has never been an artiste who had more talent".

"I was talking to him, going, 'Remember me? This led me down the path me to where I am today". Even as the disease progressed, he continued to record in his studio and play to sold-out crowds across the country.

At his final gig at the Mystic Lake Casino, he reportedly played a heartfelt rendition of "Love Sick Blues" and tear jerking performances of "By the Time I Get to Phoenix, ' 'True Grit, ' and 'Gentle on my Mind".

His song "Wichita Lineman" caught deftly not only the sense but also the mentality of a mainstream American, what he wanted and needed, and how he approached life.
