Elvis only ever appeared in one commercial in his life — for Southern Maid, his favourite jam doughnut shop. That commercial appeared on the Louisiana Hayride radio show in 1955.

But since his death in 1977, Elvis has appeared in adverts all over the world: ‘Can’t Help Falling in Love’ has been borrowed to flog bathroom fragrances; a Greek dairy company used ‘Always on My Mind’; and Coca-Cola, BMW and Nike have all been promoted with ‘A Little Less Conversation’.
