When James Keach first agreed to film Glen Campbell’s final concerts for a documentary, the tour was supposed to last for about a month and consist of 15 concerts. But it lasted for two years and 151 shows, even as the country music legend fought Alzheimer’s disease, which took a toll on both his daily life and his onstage performances.

Keach’s film, “Glen Campbell … I’ll Be Me,” was nominated for an Oscar for the song “I’m Not Gonna Miss You,” a heartbreaking farewell in which Campbell says goodbye to his wife (“the last person I will love”) and points out that he won’t remember her.

The video above, which is exclusive to TheWrap, is a scene from the film shot at the last concert Campbell ever did, in Northern California. After a shaky performance that includes a “Gentle on My Mind” guitar solo that went awry, his family and crew called it quits.

“We just knew, this is it,” his wife, Kim Campbell, says in the clip. “We were going home for the Christmas break, and we were not gonna add more shows after that.”

Campbell is now in an assisted-living facility in Nashville, Tennessee, according to Keach.

Tim McGraw will perform his nominated song on the Academy Awards on Feb. 22.
