Hubbard's fans had long requested an appearance by the veteran troubadour on the prestigious series.
The heartfelt track is accompanied by an official behind-the-scenes music video of the friends in the studio.
The single, originally released in July, gets a country revamping inspired by fans.
‘Songs From the Big Green Barn’ offers an intimate, acoustic set, as well as an outdoor show with a full band.
McGraw now ties with Garth Brooks, Kenny Chesney and Willie Nelson for No.1s, behind only George Strait.
If 'Threads' is Crow's final full-length work, as she has suggested, then it's a remarkable closing statement.
The country stars will reveal the 54th annual CMA Award nominations live on ‘Good Morning America.’
The music special will stream on iHeartRadio’s country stations, Facebook, and Youtube on September 2.
McGraw says the new album contains 'stories from the perspectives of people like you and me.'
“It is time for us to show up to the polls, be seen and heard as the great leaders we are.”
The new track follows his previous singles “I Called Mama” and the title song from the album.
At 73, Hubbard has landed a major label deal and made an album featuring Ringo Starr, Joe Walsh, the Cadillac Three and many others.
The song was written by Marc Beeson, Josh Osborne and Allen Shamblin.
Support for the virtual show on 18 July comes from American singer Michael Ray, Canadian singer-songwriter Tenille Townes, and Yorkshire-born country star Twinnie.
Originally a highlight of the band’s Country Fuzz album, the song has been significantly amped up for fans' listening pleasure.
