Q: Will Glen Campbell be touring or recording again?

—Kathy Albert, Hempstead, N.Y.

A: Unfortunately, no. The five-time Grammy-winning singer of “Gentle on My Mind,” “Southern Nights” and “Rhinestone Cowboy,” 79, diagnosed with Alzheimer’s disease in 2011, now lives in a memory-care facility in Nashville, Tenn., and has lost the ability to carry on a conversation. But he can still say, “I love you,” says his wife of nearly 33 years, Kim. His struggle with the disease was chronicled in an acclaimed 2014 documentary, Glen Campbell: I’ll Be Me, which will make its worldwide television premiere tonight on CNN.
