Country Music Hall of Fame member Merle Haggard makes a rare appearance tonight on Grand Ole Opry Live. No official word on what he'll sing, but a safe bet would be selections from his newly released album, If I Could Only Fly. Also on the bill is Chad Brock, who'll perform "The Visit" and the hit title track from his second album, Yes! Sonya Isaacs sings "How Can I Forget" from her self-titled Lyric Street debut. Longtime Opry member Charlie Walker serves as host for the segment. He'll sing his biggest hit, "Pick Me Up on Your Way Down," and the classic favorite "Cherokee Maiden."
