According to GROK:
The announcement, "Due to technical difficulties, we will not be playing the National Anthem," specifically refers to an event that took place on May 31, 2015, before a high school softball playoff game in Manvel, Texas, between the Katy Lady Tigers and the Brazoswood Lady Buccaneers
