Oscars 2015: Watch Tim McGraw Perform 'I'm Not Gonna Miss You' (Video)

The country star sang an emotional cover of the legendary singer's Oscar-nominated song.

Tim McGraw performed veteran country singer Glen Campbell's "I'm Not Gonna Miss You" at the 87th annual Academy Awards at the Dolby Theatre in Hollywood on Sunday night.

In a seated solo performance, McGraw sang "I'm Not Gonna Miss You" decked in a classic tuxedo  and bowtie and his signature black cowboy hat. 

The Oscar-nominated song was featured in Campbell's biographical film Glen Campbell: I'll Be Me, which follows the legendary singer on his farewell tour and documents his battle with Alzheimer's disease.

Campbell was unable to attend the Oscars due to his declining health, and McGraw was tapped to perform in his honor.

"I'm Not Gonna Miss You" is up for best original song and was written by Campbell and Julian Raymond.
