Radar Station B-71: The B-71 radar station also known as Klamath River Radar Station, Crescent City Radar Station, Trinidad Radar Station was an Army Air Force early warning station in World War II.  It is a rare survivor of a World War II early-warning radar station.  It was constructed as a disguise to look like a farmhouse.  To guard against potential invasions, the U.S. Army built "farm" buildings; the cinderblock structures, complete with shingled roofs, and fake windows and dormers, housed an early-warning radar station.  From the air, the sea, and even the road, these buildings appeared to be part of a working farm.  In fact, they housed a diesel generator, electronic equipment, and two 50-caliber anti-aircraft guns.  This is one of 65 that were built all along the western coast of America during World War II.  It is located on Coastal Dr. just south of the mouth of Klamath River.

Its performance was done by numerous artists, including the Alexandrov Ensemble.  The original 1945 is highly triumphal with its brass fanfares and ecstatic chords extended upward with the aid of trumpets, as part of the V-E Day celebrations.  That arrangement by A. Alexandrov is very much in the tradition of final choruses in 19th-century Italian grand opera, and shows how he originally envisaged this composition.  There are many versions of the song.
