Tim McGraw will perform a very special tribute to Glen Campbell at the upcoming 2015 Academy Awards.

The country superstar will perform Campbell's Oscar-nominated song, 'I'm Not Gonna Miss You,' during the broadcast. The song -- which appears in the documentary film 'Glen Campbell: I'll Be Me' -- looks back on Campbell's life and also reflects on everything his progressing Alzheimer's is slowly taking from him.

Written by Campbell and Julian Raymond, the track is nominated for Best Original Song in the 87th annual Academy Awards. Campbell has been living in an assisted care facility for most of the last year, and his wife, Kim, has stated that he will never perform in public again. The song is from his final recording session, and McGraw calls it "a powerful song from one of the true legends of the music industry."

'Good Morning America' anchor Lara Spencer broke the news of McGraw's performance on Thursday morning (Jan. 29). The 2015 Oscars are set to air live from the Dolby Theatre in Hollywood on Feb. 22 beginning at 7PM ET on ABC.
