Glen Campbell has recorded his final song and the result, "I'm Not Gonna Miss You," is a poignant, confessional tune that serves as a stunningly personal coda to a career spent entertaining millions throughout the world.

Recorded in Los Angeles in January 2013 and written by the pop-country legend with Julian Raymond, who produced the track, "I'm Not Gonna Miss You" was penned specifically for the new documentary Glen Campbell: I'll Be Me. Among those appearing in the film are Bruce Springsteen, Bill Clinton, the Edge (from U2), Paul McCartney, Jay Leno, Vince Gill, Jimmy Webb, Taylor Swift, Blake Shelton, Sheryl Crow, Keith Urban, Brad Paisley, Steve Martin, Chad Smith and the Band Perry.

"I'm Not Gonna Miss You," available through digital retailers on September 30th, deals with the heartbreaking realities of Alzheimer's and the losses that Campbell has faced since he was diagnosed with the disease in 2001. The documentary further details what the entertainer's life has been like and how his family has coped with the struggle, which has had the 78-year-old Country Music Hall of Fame member admitted to a special care facility in Nashville.

In addition to the new song, Big Machine Records will release a soundtrack for the film that also features the Band Perry, who previously paid tribute to Campbell during the 2012 Grammy Awards. Campbell's daughter Ashley — among the family members who toured and performed with Campbell on his Goodbye Tour — also contributes an original song to the project. The full soundtrack album is expected later this fall, while a soundtrack EP will be released September 30th. (See the track listing below.)

Directed and produced by James Keach (producer of the Oscar-winning Walk the Line) and produced by Trevor Albert (Groundhog Day), Glen Campbell: I'll Be Me opens in theaters in New York on October 24th, followed by a national release in 50 cities.
