Ray Charles In Music Hall America (1976)

Mike Douglad and Ray Charles, possibly from this show.

Music Hall America was a syndicated 1-hour country music variety TV show,  that ran from 1976 to 1977. It was taped at Opryland in Nashville, produced by Viacom and directed by Lee Bernhardi.
In 1976 the series ran for 26 episodes, each with a different host, a.o. the Statler Brothers, Burl Ives, Mike Douglas, Jim Nabors, Kenny Rogers, Merle Haggard, Pat Boone, Ray Charles, Roy Rogers and Dale Evans.  
The happy tagline was: Come along and join the fun, come one, come all, come everyone! Come to the Music Hall America! 
Ray Charles was headlined in a program with Tom T. Hall, Ronnie Prophet, Charlie McCoy, comedian Rip Taylor and Sandi Burnett. He performed America The Beautiful.
It's unclear if the footage has survived (but Archival Television Audio Inc. may have a copy - cf. this).
