FOUR year 12 students from All Saints Catholic Senior College at Casula performed at Sydney Entertainment Centre last week.
They sang the national anthem before the Sydney Kings v Perth Wildcats basketball game.
The girls are in the college choir, which regularly performs at formal assemblies and liturgies and is led by their music teacher, Kate Penfold.
"Students were selected to perform based on a demo recording I sent the community relations manager at the Sydney Kings," Ms Penfold said.
"The event went well, with college staff and students attending to cheer on the students. "They did get a little nervous under the bright lights, but managed a very nice rendition of the anthem."
