Glen Campbell performs at the Hollywood Bowl on June 24, 2012, as part of his goodbye tour. Before Campbell, who announced in 2011 that he was living with Alzheimer's disease, took the stage Sunday evening, a cast of singing admirers lined up to pay homage. They included Lucinda Williams, Kris Kristofferson and Jackson Browne.
