Singer Glen Campbell dies aged 81

Campbell's family confirmed that the musician died on Tuesday at age 81 in a statement on his personal website.

The Country Music Hall of Fame artist released his final album earlier this year titled "Adios". The seeds of his career were planted at the age of 4 when he received a guitar that had been ordered from a Sears, Roebuck & Co. mail-order catalog.

In his Glen Campbell tribute, Jimmy Webb wrote on his official Facebook page that his longtime friend and co-collaborator's passing was inevitable, given his recent and well-documented health issues. Jackson heard the news from Campbell's daughter, his goddaughter. "He always gives a lot of props to his fans, so I try to take after him in that respect". When he was just 4 years old, his father bought him a $5 guitar from Sears, probably not realizing that he was setting his son on a course for global stardom. This was all despite Campbell being unable to read music. The popularity of the song led to a nationwide country-music craze that saw mechanical bulls and cowboy hats fill bars across the nation.

Campbell's fifty-plus years in the business has produced such legendary works as "Rhinestone Cowboy" (1975), "Gentle on my Mind" (1967), and "By the Time I get to Phoenix" (1967).

The singer surprised the crowd with a cover of Campbell's "Gentle on My Mind", a handsome tribute to a man who passed away earlier that evening after a battle with Alzheimer's.

John Mayer paid tribute to Glen Campbell last night during his Nashville concert. He and Tucker broke up acrimoniously in 1981, but he went on to find Christ and end his substance abuse.

"Something I will be able to hold onto for the rest of my life".

Webb also pointed that he had great respect for Campbell for deciding to tour late in his life, despite struggling with the effects of Alzheimer's.

Campbell was small town country boy who went on to win six Grammy awards and achieve every milestone a musician can reach.

For many fans, Campbell was everywhere.

But Campbell himself remained upbeat.

"He wanted to tell the story of his Alzheimer's disease", said director James Keach, who also directed the Johnny Cash biopic "Walk the Line".

Sen. Susan Collins (R-ME), co-chair of the Congressional Task Force on Alzheimer's Disease and chair of the Senate Special Committee on Aging, said in a statement that she and others will remember Campbell for his advocacy efforts.
