About a year ago, the album Honky Tonk Man: Buck Sings Country Classics was released. Here's the summary from Amazon:
2013 collection of unreleased tracks from the late Country great. Given the opportunity to record a large group of songs that reached far beyond his own best-known works, Buck enjoyed the rare chance to stretch out and have fun performing the hits of other Country singers. Over the course of this collection, pulled from the vast trove of material Buck recorded for Hee Haw, Owens provides us with a concise tutorial on the history of country music. Many of the songs Buck recorded for Hee Haw were originally recorded by some of Buck's biggest and earliest influences like Bob Wills & His Texas Playboys, Hank Williams, Jack Guthrie and Hank Snow amongst others. The CD's title track, 'Honky Tonk Man,' is a song first popularized by Johnny Horton in 1956. Thirty years later, it became an even bigger hit for Dwight Yoakam (about a decade after Buck had recorded the song for Hee Haw).
This is a great collection that we highly recommend. Here's the opening track:
