Campbell announced his Alzheimer's diagnosis in 2011, which he followed with the Goodbye Tour and the documentary film I'll Be Me.
"It was a magical and moving evening for everyone, and it was clear the memorable music he created over the course of more than 50 years had not left him", explains Janice Wade-Whitehead, Alzheimer's Tennessee President & CEO.
If his words, his songs and his story are a comfort to even one of the families who are battling this dread disease, he will have made a difference that will last long after his music is just a memory. "I'm a jazzer. I just love to get the guitar and play the hell out of it if I can".
It will be perhaps his greatest contribution from a list of accomplishments a mile long.
"He was a wonderful session musician as well". "Those songs had melody, chord progression and lyrics - wow!" He was a very rare talent. "His impact on the industry will remain gentle on our minds". He began performing around Los Angeles with a four-man country band. "Nobody liked a Jimmy Webb song as much as Glen!"
Even as the country genre slipped in a niche in a changed world.
From 1969 to 1972, The Glen Campbell Goodtime Hour was a hit on the CBS network as part of their "rural" block of programming. Guests on the show ranged from Ray Charles to Tony Bennett. "He performed Danny Boy and the crowd loved it".
There was of course a dark side to his meteoric rise. No one in the intervening years has been able to mix and adapt those sounds quite as well as he did. He admitted abusing drugs and cocaine.
The tributes showed Campbell's widely felt influence, with country stars like Charlie Daniels and Lady Antebellum chiming in alongside Peter Frampton of The Who, Ringo Starr of The Beatles and Sheryl Crow. Glen prevailed, but perhaps he eventually paid the price.
Growing up in the early 60s we constantly overheard names of musicians in conversations between my parents or their friends.
The song was an answer to a Campbell request, Webb recalled in 2012. His voice and his brilliance on the guitar were unparalleled.
American singer, songwriter, musician, television host and actor Glen Travis Campbell died on August 8 of Alzheimer's disease, eight years after being diagnosed. They worked together often; Clark knew what he was talking about. "What a musician. His contribution is and will likely always be unmatched". "I will always love you, Glen!" said Dolly Parton.
"Glen Campbell was a Champion for the Cause and a true "AlzStar" who shined a light on this disease like never before", Wade-Whitehead, continued.
