Shoppers stunned by surprise opera performance in market

This is the remarkable moment on Friday when market workers in the Guatemalan capital appeared to suddenly break into song, stunning local shoppers with an incredible operatic performance.

The video shows a man, who appears to be working behind a stall selling water, begin to belt out the opening bars of "Libiamo ne' lieti calici" from Verdi's La Traviata.

Then, what appears to be one of the market cleaners, joins in as he sweeps the floor.

Finally, a woman dressed as a market seller adds her own wonderful soprano voice to the impressive performance.

When the trio finishes their rousing rendition, the stunned market-goers break into spontaneous applause.

Of course, the three singers were in fact not market workers but professional opera singers who were taking part in a project organised by Guatemalan authorities to promote culture and art.
