The pilot episode of Austin City Limits, the longest-running live music television show in history, taped on October 17, 1974 at KLRU's Studio 6A, located in Communications Building B on the University of Texas campus. Willie Nelson was the first performer. The first song sung? "Whiskey River." Final song of the show? "Roll in My Sweet Baby's Arms."
By way of the "Austin" Jigsaw Puzzle's artwork, Studio 6A would be to the left of the University of Texas Tower.
