Cadbury 'Crunchie Rock' by Fallon London

Cadbury has launched its new Crunchie Rock sweets with a retro rock themed ad by Fallon.

The ad features an unsuspecting man in a caravan singing Tina Turner's classic 'We don't need another hero' to himself in the mirror.

Crunchie's 'Friday Feeling engineers' arrive and transform his room into stage complete with backing-singers, dry ice and a live audience.

The campaign will be supported by a rock-themed national outdoor and digital campaign.
