One of several songs from Argybargy with a catchy, happy tune and a dark subject, in this case apparently drug smuggling. "[H]igh up on the Khyber" almost certainly refers to the Khyber Pass in Afghanistan / Pakistan, through which passes or at least historically passed a large percent of the world's supply of opium / opiates. Again, "discovered the shipment of Moroccan" presumably refers to hidden drugs, for which he is now "[b]ehind prison walls and gates".
