Countrypolitan legend Glen Campbell was awarded a Lifetime Achievement Award at the Grammys in February. In one of the most memorable moments during the telecast, Campbell sang his signature hit "Rhinestone Cowboy" as a goodbye.
What he is calling the "long goodbye" continues this summer on a national tour, and Campbell, with three of his children joining him in his backup band, will headline the Sandy Amphitheater Monday.
In June 2011, Campbell said he had been diagnosed with Alzheimer's disease six months earlier, after enduring memory problems for years. Last August saw the release of his final album, "Ghost on the Canvas," with collaborators including Paul Westerberg, Jakob Dylan, Chris Isaak, Rick Nielsen and Billy Corgan.
