Students who were singing on stage crashed down to the ground when a stage gave way beneath them.
The choir on stage
Twenty-five choristers were hospitalized after a 10-foot-high wooden platform collapsed at Beihang University in Beijing on Saturday.
The South China Morning Post reports that after the incident, an audience member captured footage on a cell phone that shows the 100-strong group sing "Happy Birthday" to mark the 30th anniversary of the college's aeronautical engineering school.
But dozens of them then suddenly disappeared mid-song, sparking screams from the audience.
According to The Telegraph, none of the hospitalized students suffered serious injury.
The university has canceled future events due to be held in the 880 capacity Chenxing Music Hall as it investigates the incident, reports Metro.
