Prior to this date in 1944, the sound Grand Ole Opry was changed forever by Monty Mountjoy's refusal to be left out of their performance.

Prior to the performance by Bob Wills & The Texas Playboys on December 30th, 1944, you would have not heard the sound of drums.  Drums were not allowed on stage at the Opry, but Monty Mountjoy simply wouldn't be told "no", and moved his set on stage at the last minute, despite protests from the Opry.  As the first notes of "New San Antonio Rose" began, the sound of the Grand Ole Opry would never again sound the same.
