Garrett pointed me to the following article that tells me I'm wrong about the campfires:
"In 1996 the American Society of Composers, Authors and Publishers (ASCAP) told the Girl Scouts of the USA that scout camps must start paying a licensing fee to sing any of the 4 million copyrighted songs that ASCAP controlled (Walker and Fagan). This included girl scout staples such as "Happy Birthday". Many camps went songless for months, until newspaper and talk show attention generated enough outrage that ASCAP was forced to say that they had no intention of prosecuting girl scout camps for violations of singing songs around the campfire. But in backing down, ASCAP still insisted that they still might prosecute camps for playing background music without a license. Though most citizens would bristle at ASCAP’s attempts to charge the girl scouts, as a copyright holder the law is on their side, and the girl scouts’ only defense would be fair use (but only as long as fair use remains a defense)."
