Who was she who sang the anthem?

PATRIOTISM QUESTIONED. During the flag ceremony of a government office attended by its officials and employees, a woman showed up from nowhere and took part in the singing of the national anthem. She stood at the foot of the flagpole. She had a good voice and sang the anthem like the way the famous Charice sang it. The security guard tried to shoo her away but the office head stopped him.

NOTHING WRONG. He said the woman did nothing wrong. “She did barge in but she sang the national anthem with patriotic fervor,” the boss said. After singing she left, took a PUJ, and was gone. Who was that woman? Some employees said she could be a frustrated singer.
