"Lunatic Fringe" is a song by the Canadianrock band Red Rider from their 1981 album, As Far as Siam. Guitarist Tom Cochrane wrote the song after becoming concerned about a resurgence of anti-Semitism in the 1970s, and was also inspired after reading a book about Raoul Wallenberg, who rescued Jews from The Holocaust during World War II. Some sources have incorrectly cited the murder of John Lennon as the song's primary inspiration; in fact, Cochrane had already written the song before Lennon was killed, but recorded the song's first demo the evening of the murder. He has stated that his feelings about the event, and how it echoed the theme of his song, galvanized him to release the song as a single despite advice from the record label that the song wasn't commercial enough.
The song starts with a sinister, low keyboard tone, punctuated by a "double tap" of two medium-pitched short notes. The song then progresses with its main theme, ending dramatically with ambulance sirens and final guitar riffs. Throughout the body of the song is a low, powerful bassline.
The song is a radio favorite, and has received regular airplay in the United States and Canada. It reached #11 on the Rock Radio Airplay Chart in Billboard in September 1981, and was awarded a SOCAN Classic award in 2009 by the Society of Composers, Authors and Music Publishers of Canada for reaching the 100,000-airplay mark on (Canadian) domestic radio.
That song was a big influence for Cincinnati's legendary rock station WEBN that it somehow created their very own now but infamous slogan, "The Lunatic Fringe Of American FM" the slogan got its debut in 1984.
