C.G. Conn Ltd., sometimes called Conn Instruments or commonly just Conn, was a United States manufacturer of musical instrument incorporated in 1915.
 It bought the production facilities owned by Charles Gerard Conn, a major figure in early manufacture of brasswinds and saxophones in the USA.
 Its early business was based mainly on such instruments, which it manufactured in Elkhart, Indiana.
 During the 1950s the bulk of its sales revenue shifted to electric organs.
 In 1969 the company was sold under bankruptcy to the Crowell-Collier-MacMillan publishing company.
 Conn was divested of its Elkhart production facilities in 1970, leaving remaining production in satellite facilities and contractor sources.
 The company was sold in 1980 then again in 1985, reorganized under the parent corporation United Musical Instruments (UMI) in 1986.
 The assets of UMI were bought by Steinway Musical Instruments in 2000 and in January 2003 were merged with other Steinway properties into a subsidiary called Conn-Selmer.
 C.G. Conn is currently a brand of musical instruments manufactured by Conn-Selmer.

The Gesellschaft der Freunde alter Musikinstrumente (GEFAM) ("Society of friends of old musical instruments") was founded in 1951 in Zurich, Switzerland, by a number of music lovers and collectors of historical musical instruments.
 It is still the only society in the German speaking part of Europe (Germany, Austria, Switzerland, Lichtenstein) that is concerned mainly with old musical instruments.
 Thanks to its base in Switzerland it has a multicultural and multilanguage profile, visual in its international list of members.
 Today there are around 200 members (individuals and institutions), mainly in Europe, but also on other parts of the globe.
 The spectrum includes specialised museums and collections of old musical instruments, researchers and instrument makers as well as private collectors and enthusiasts.

"There's A Star-Spangled Banner Waving Somewhere" is a patriotic anthem written in 1942 by Paul Roberts and Shelby Darnell (a pseudonym for producer Bob Miller).
 The song was completed, along with other tunes, on Swan's Island, Maine, where Paul Roberts visited and performed with his soon to become wife, Annie Marrithew, during World War II.
 The song enjoyed its greatest popularity during the war years.
 The "somewhere" in the title of the song refers to an idealistic version of heaven reserved for the brave U.S. soldiers fighting the Axis Powers, somewhat akin to the concept of Valhalla.
 The verses are a narrative of a young man who is crippled, but still yearns to fight and earn his place in this patriotic afterlife.
