Years ago, the three artists and a few others got together often and played as “The Traler Park Show.” They’ve added the name “Revival” for this show in honor of the Ryman Auditorium, known as the “Mother Church of Country Music.” All proceeds from the show will benefit the Opry Trust Fund, which provides financial assistance to members of the country music industry in times of need. Tickets are $20 and will be available at ryman.com, opry.com, (800) SEE-OPRY and the Ryman and Opry House box offices, beginning April 24.
