A routine day of shopping for groceries at John Lewis Foodhall from Waitrose turned into a grocery store opera when five singers performed a rousing rendition of the Italian classic Funiculì, Funiculà. This creative and fun musical flash mob is from Sacla’ the Pesto Pioneers and Italian foodies favourite brand who served up a great surprise by staging this impromptu Opera in the food aisles. How cool would it be to have opera singers perform each time you went shopping for groceries.
