Grocery Store Worker Wows Shoppers With His Own Rendition of 'O Holy Night'

One man may be able to quit his day job after he showed off his singing chops at the supermarket where he works.

In a moment captured on video, Gilly Assuncao, who works at Russo's in Watertown, Mass., belted out "O Holy Night," and he became an internet sensation when it was shared to the store’s Facebook page.

The clip has been view more than 55,000 times since it was posted Saturday, which has come as a complete surprise to Assuncao.

“I was not expecting that at all,” he said.

Assuncao, who works in the store’s deli, was working Friday night as a man came to set up the sound system for carolers who were set to perform at the store on Saturday.

“I heard him say, ‘Test 1, 2, 3’ and I offered my help and said, ‘Do you want me to sing a song while you [fix] the sound system?’” Assuncao said. “So I sang a song and my boss heard and he asked if I could sing a few songs on Saturday."

Assuncao, who said he was a professional singer before he moved to America from Brazil two years ago, jumped at the opportunity, singing “O Holy Night” for customers.

Getting back into show business has been a goal for the 23-year-old.

“It’s always been my dream," he said. "I hope it goes somewhere. I have the dream to study at Berklee College of Music,
 but it’s too expensive."

But for now, Assuncao's holiday performance at the store earned him an encore, and he will continue singing there through the Christmas season.

"I am really grateful for all the support," he said. "I am very happy that people enjoyed me singing."
