Glen Campbell made a name for himself with songs like “Wichita Lineman,” “Galveston,” and “Rhinestone Cowboy,” all of which have become cornerstones in the history of country music.

In a heartbreaking turn of events, the 75-year-old Campbell announced earlier this summer that he has been diagnosed with Alzheimer’s, which is slowly eroding his memory.

Last night on ABC, Campbell sat down to talk about his upcoming album (the excellent Ghost on the Canvas), his plans for a farewell tour, and the difficulties of looking back when your memories are already slipping away.

“I have been blessed,” he said during the broadcast. “I’m not that bright, but God gave me a break.”

Campbell remains in excellent spirits, though as the video makes clear, he increasingly leans on his wife Kimberly for support.

EW’s Dave Karger had a similar experience when he visited Campbell and his wife at his home in Malibu for a feature in the new issue of Entertainment Weekly that hits newsstands this Friday.

“Age is a word—I’m 75 and I feel like a kid,” Campbell told Karger. Based on the masterful execution of Ghost on the Canvas and the verve that he still possesses when he performs, that appears to be true. “There’s a magical thing that happens when he walks on stage,” Kimberly told EW. “All of a sudden it’s like bam, he’s Glen Campbell.”

Will you be seeing Campbell on his final tour? And what do you think of the general concept of a farewell album, as done previously by greats like Johnny Cash and Warren Zevon?
