To get more traffic into Burger King drive thrus in December, we rewrote "Driving Home for Christmas" (one of Britain's biggest Christmas songs) to "Driving (thru the) Home (of the Whopper) for Christmas." The sat-nav singing music video features turn-by-turn directions to Burger King drive thrus on the most travelled routes at Christmas. Then we chopped the full track into 23 targeted localised radio commercials, guiding drivers to their closest Whopper establishment.
