Shoppers at Welland's Seaway Mall were in for quite the surprise, when the Port Colborne Operatic Society staged a flash mob.
Members broke out into song and dance on Saturday.
They sang several ABBA hits; including Mamma Mia, Dancing Queen and Waterloo.
They were promoting the society's upcoming production of Mamma Mia the musical.
February 22nd will be the opening night at Lakeshore Catholic High School. The last show will be on March 8th.
This wasn't the first time a flash mob took over Seaway Mall. Chorus Niagara went viral back in 2010, when members sang Hallelujah in the food court.
