Glen Campbell is a Grammy-winning country music icon, but his wife Kim Campbell says one of the most important things the legend has done in his life is to "help remove the stigma of Alzheimer's disease."
Glen was diagnosed with the disease in 2011, went public and embarked on a farewell tour with his family, including his wife and their three children -- Cal, Shannon and Ashley -- which ended in 2012. Kim said the experience touring with their father only brought the immediate family closer together and really shed light on the disease.
