Clenn Campbell, family, celebrate this weekend

As if the opening today of a documentary on his Goodbye Tour and the release last week of his final recording weren't enough to bring a measure of happiness to Glen Campbell and his family, the country superstar and his wife Kim will celebrate their 32nd wedding anniversary Sunday.

Glen Campbell: I'll Be Me, opening today in New York and Nashville and soon expanding to more cities, follows the Wichita Lineman singer on his final tour and chronicles his medical treatments in the wake of his 2011 diagnosis of Alzheimer's disease. The couple's three children from their marriage, and other family members appear in the film and talk about they coped with the disease.

The documentary comes on the heels of the release of the poignant single I'm Not Gonna Miss You, billed as his final recording.

In a new interview with Rolling Stone Country, Kim Campbell says that her husband has "always been open and honest about his live and everything that's happened to him and its journey in his faith. We have a great family and we love being together.''
