That same year, film legend John Wayne chose Campbell to appear with him in the movie Western True Grit, which earned the singer a Golden Globe nomination for Most Promising Newcomer. In the mid-1960s he also had a brief stint touring with the Beach Boys after Brian Wilson left the band following a mental breakdown. He also leaves behind a legacy of Alzheimer's Disease educational advocacy that his family furthered into his final years.
Glen Campbell was married. The trek ran through November 2012, and featured several of Campbell's children playing in his backing band.
Campbell was the subject of the 2014 documentary I'll Be Me, which chronicled his farewell tour and battle with the debilitating disease.
