There's nothing like a 1971 John Denver song to pique my interest and completely make my day.

When I set out to find out what this #ForeverCountry movement is about, that was the first clip I clicked. It was Tim McGraw singing a tiny piece of Denver's "Take Me Home, Country Roads.”

Then I clicked on Dierks Bentley. He kept the song going with the “dark and dusty, painted on the sky” lyric.

Brad Paisley stayed on that Denver path with “almost heaven, West Virginia.”

Keith Urban added his voice with “Blue Ridge Mountains, Shenandoah River.”

And Luke Bryan came in on “to the place I belong.”

(It dawned on me after all this that watching the artists in order would have made much more sense, but hindsight’s 20/20, right?)

What I now know is that in order to celebrate the 50th anniversary of the CMA Awards, the Country Music Association Awards is creating the "Forever Country" promotion with what's being described as "the biggest music video in country music history."

When it’s all said and done, by Sept. 20, there will be 30 artists involved in this medley of John Denver’s “Take Me Home, Country Roads,” Willie Nelson’s “On the Road Again” and Dolly Parton’s “I Will Always Love You.”

Other artists already revealed for the project include Nelson, Parton, Eric Church, Kacey Musgraves, Charley Pride, Carrie Underwood, Faith Hill, Lady Antebellum, Reba McEntire, Alabama, Darius Rucker, Rascal Flatts, Alan Jackson, Blake Shelton, Randy Travis and Trisha Yearwood.

The video reflects this year's awards theme, "Then, Now, Forever Country." Paisley and Underwood host the 50th annual CMA Awards from Nashville on Nov. 2 on ABC-TV.
