For its latest campaign, McDonald’s seems to have taken inspiration from the the nursery rhyme ‘Sing a song of six pence’. But rather than having “four and twenty blackbirds baked in a pie” singing to a king, it has instead added a touch of music to its Big Mac boxes. Yesterday, as selected McDonald’s customers in Auckland opened their Big Mac boxes, they were blasted by song straight from the burger’s container. The singing boxes were part of McDonald’s global ‘imlovinit24’ initiative, which sought to share 24 moments of joy to millions in 24 hours.
