Veteran country star Glen Campbell was out of his full-time care facility so that he could celebrate the Christmas holiday with his family in Nashville, Tenn. He has been in the facility since April, due to an ongoing battle with Alzheimer's.

Campbell, 78, has been very public about his battle with the disease, bravely staging a farewell tour after his diagnosis in 2011 and even allowing camera crews to capture those performances for a documentary. "Glen Campbell: I'll Be Me" was released in October to movie theaters throughout America, and it subsequently earned the filmmakers a Critics Choice nomination for "Best Documentary Feature."

The documentary features commentary from fellow musicians Blake Shelton, Sheryl Crow, Keith Urban, Brad Paisley, Taylor Swift and Vince Gill, as well as friends and fans like Steve Martin, Bruce Springsteen, U2's the Edge, Paul McCartney, Jimmy Webb, Jay Leno and Bill Clinton.

Back in June, Campbell's wife, Kim, described his time in the Nashville long-term care facility.

"He has longtime friends here in Nashville who come to play music for him and give him hugs," she said. "He has activities and therapies to stimulate him and help him experience daily moments of success. His life is filled with love and laughter and he is being cared for round the clock by people who specialize in Alzheimer's care and happen to adore him."

"Glen Campbell: I'll Be Me" features his final recording, "I'm Not Gonna Miss You," and its moving music video. Campbell went into the studio in January 2013, just months after his final public performance to record "I'm Not Gonna Miss You," a rumination on everything that Alzheimer's is slowly taking from the singer as he enters its advanced stages. Campbell co-wrote the song with Julian Raymond and recorded it specifically for the documentary film.
