The Clear Channel memorandum contains songs that, in their titles or lyrics, address topics that relate to the September 11 attacks, such as airplanes, collisions, death, violence, explosions, the month of September, Tuesday (the day of the week the attacks occurred) and New York City, as well as general concepts that could be connected to aspects of the attacks, such as conflict, the Middle East, the sky falling, and weapons. Also included under the ban were several happy and celebratory songs (including
Louis Armstrong's "
What a Wonderful World"), as Clear Channel believed playing joyful music in the aftermath of the attacks was inappropriate.
WASH, a Clear Channel-owned station in Washington, D.C., reportedly played
Kool & the Gang's "
Celebration" while the memorandum was being circulated, "which brought a polite if reproachful call from one listener, who was assured by the station the song's broadcast was a mistake." ==List of songs==
