This refers to a world famous scene of a Levi’s commercial that relaunched basics in 1985. It featured teen idol Nick Kamen who took off his jeans in a packed launderette to wash them, while Marvin Gaye’s ‘I heard it through the grapevine’ played in the background. It was made by British ad agency Bartle Bogle Hegarty.
