Europe '72 Volume 2: Europe '72 Volume 2 is a live album by the rock band the Grateful Dead.  It is a two-CD set which features 20 tracks from the band's Spring 1972 tour of Europe.  As such, it represents a belated sequel to the band's original three-LP 1972 release, "Europe '72".  Around the time of the production of the massive "" box set in 2011, Grateful Dead archivist David Lemieux was charged with the task of developing this follow-up compilation, nearly four decades later, without repeating any of the songs that appeared on "Europe '72".

The artwork for the release is by Stanley Mouse, who, along with his late partner, Alton Kelley, created the recognizable images for the original release.

France–United Kingdom relations: France–United Kingdom relations are the relations between the governments of the French Republic and the United Kingdom of Great Britain and Northern Ireland (UK).  The historical ties between the two countries are long and complex, including conquest, wars, and alliances at various points in history.  The Roman era saw both areas, except Scotland and Northern Ireland, conquered by Rome, whose fortifications exist in both countries to this day, and whose writing system introduced a common alphabet to both areas; however, the language barrier remained.  The Norman conquest of England in 1066 decisively shaped English history, as well as the English language.  In the medieval period, the countries were often bitter enemies, with both nations' monarchs claiming control over France.  The Hundred Years' War stretched from 1337 to 1453 resulting in French victory.  Britain and France fought a series of five major wars , culminating in the Coalition victory over Napoleon in 1815.  After that there were some tensions, but peace generally prevailed and as the 19th century progressed, the relationship became better.  Closer ties between the two began with the 1904 Entente cordiale, particularly via the alliances in World War I and World War II, wherein both countries fought against Germany, and in the latter conflict British armies helped to liberate occupied France from the Nazis.  Both nations opposed the Soviet Union during the Cold War and were founding members of NATO.  In recent years the two countries have experienced a quite close relationship, especially on defence and foreign policy issues; the two countries tend, however, to disagree on a range of other matters, most notably the European Union.  The British press relishes the chance to refer to France and Britain as "historic rivals" or emphasize the perceived ever-lasting competition that still opposes the two countries.
