George Jones is marking the end of an era this year with his retirement/farewell tour, which he’s aptly dubbed “The Grand Tour.”

Jones and his former wife Tammy Wynette were no longer married when the long-reigning King & Queen of Country Music played their final Capital Region concert together. When and where was the concert? And who was their opening act?

The answer will be posted on Monday (March 18).
