The synchronicity of 'The Wizard of Oz' and Pink Floyd's 'Dark side of the Moon' - YouTube
US History teachers that use Henry Littlefield's Wizard of Oz analogy device in a lesson about the Gilded Age can use Pink Floyd's "Dark Side of the Moon" synchronicity as a quick device to peak their interest. This video scrambles the music at parts to move the the best examples, but the inclusion of video, music and lyrics is excellent. You can also watch it just for fun.
