Country music's most powerful Grammys moment may have come before the show even began. Glen Campbell's wife Kim took the stage to accept his Best Country Song award during the 2015 Grammys pre-show webcast. The strength she displayed as she talked about the 78-year-old's final recording brought everyone in the room to their feet.

Campbell's 'I'm Not Gonna Miss You' won the Grammy, and Kim Campbell accepted along with the song's co-writer, Julian Raymond. Raymond thanked family, Scott Borchetta, the Big Machine Label Group and the director of 'I'll Be Me,' the documentary that included the award-winning song. The country legend is in the late stages of Alzheimer’s Disease and was not on hand to accept.

“It’s been an amazing journey, he’s been so courageous in bringing attention to Alzheimer’s,” Kim Campbell said before providing a brief update on her husband's condition.

“He is healthy and cheerful and I know first and foremost he’d want to thank God," she revealed.

Like the film, 'I'm Not Gonna Miss You' was written to bring awareness to Alzheimer's, a disease Campbell has been battling for four years. He helped write the song with Raymond and included it on the soundtrack.

Campbell's Best Country Song win came on the heels of the Band Perry's win in the Best Country Duo/Group category. Their cover of 'Gentle on My Mind,' Campbell's hit from 1967, earned that honor.
