Diplomatic Immunity - Season 1 Episode 7 Climb Every Mountain

For once it is Leighton who must try to save the Fe'ausians from their own greed, as they plan to sink all the money they have made from phosphate mining Kakapu Atoll into an extremely dodgy West End musical. Of course, most of the staff at the Auckland embassy of The Most Royal Kingdom of Fe'ausi get bitten by the theatrical bug and want roles in the musical, whose show-stopping numbers include, naturally, a big fat finale called Knocked The Bugger Off.
