Watch 'Forever Country' gather country's best & brightest for all-star music video

To celebrate 50 years of the CMA Awards, the Country Music Association brought country's best and brightest together for the song "Forever Country" -- and now there's an all-star music video to match.

CMA Announces 'Forever Country' Single & Music Video in Honor of 50 Years of CMA Awards

The video -- which premiered during Dancing With the Stars on Tuesday night (Sept. 20) -- features appearances by all 30 of the song's singers.

The medley features a combination of three songs: John Denver's 'Take Me Home, Country Road," Dolly Parton's "I Wil Always Love You" and Willie Nelson's "On the Road Again."
