The song was inspired by "Chasing after Danger", the memoirs of Squadron Leader Terence O'Brien, a decorated pilot from World War II. O'Brien was one of the pilots who flew missions against the harbor in Brest where the German battlecruisers Scharnhorst and Gneisenau were penned in by a British blockade. 'Salmon and Gluckstein' - the name of a major chain of tobacconists in Britain - were code words used to refer to the two battlecruisers.
