Question: Which occupation do both Grażyna Miller and Richard Fariña follow ?  
Context: The Swallow Song is a folk-music song written in 1964 by Richard Fariña.  It was likely based on Dimitrie Cantemir's "Los Paxaricos", which contains an identical melody.  The song was recorded on Richard & Mimi Fariña's second LP, 1965’s "Reflections in a Crystal Wind " and was included on Joan Baez's 1995 album "Ring Them Bells". In condensed matter physics, the probability of occupation shows how likely it is for a given energy level to be occupied.  Fermions such as electrons follow a Fermi–Dirac distribution and bosons such as phonons and photons follow a Bose–Einstein distribution. The Latin American Wars of Independence were the revolutions that took place during the late 18th and early 19th centuries and resulted in the creation of a number of independent countries in Latin America.  These revolutions followed the American and French Revolutions, which had profound effects on the British, Spanish, Portuguese and French colonies in the Americas.  Haiti, a French slave colony, was the first to follow the United States to independence, during the Haitian Revolution, which lasted from 1791 to 1804.  From this emerged Napoleon Bonaparte as French ruler, whose armies set out to conquer Europe, including Spain and Portugal in 1808.  The Peninsular War, which resulted from the Napoleonic occupation of Spain, caused Spanish Creoles in Spanish America to question their allegiance to Spain, stoking independence movements that culminated in the wars of independence, which lasted almost two decades.  At the same time, the Portuguese monarchy relocated to Brazil during Portugal's French occupation.  After the royal court returned to Lisbon, the prince regent, Pedro, remained in Brazil and in 1822 successfully declared himself emperor of a newly independent Brazil.

Later this unit was redesignated a General Service Regiment.  The unit was formed from some regular Army officers and enlisted men, trained in the United States, then shipped overseas early in World War II to England.  They were the vanguard of many others to follow, including infantry and armored troops.  Their purpose was to build facilities in preparation for those to follow.  After the Normandy Invasion, they followed the front lines constructing roads, railroad bridges, hospitals, and other infrastructure needed by the advancing Armies.  Continuing through until surrender by Germany in 1945, the unit stayed on as part of the Army of Occupation.  Many of the troops in the units were among those who were overseas for the longest periods of all in World War II.
