Woody was an avid reader; he consumed books, and wrote his response to the text in the margins. In the late 1930s, he read the Rubaiyat of Omar Khayyam, the quatrains written by the 11th-century Persian poet; when translated by Edward Fitzgerald and published in 1859, this collection had a lasting influence on English poetry. Woody's copy of a later edition with his notes in the margins of each page is now owned by a private collector, and reflects how Woody thought and philosophized about each word he read. According to Moe Asch, when Woody and Cisco spent time studying the Sacco and Vanzetti episode, Woody came up with "the idea to do the Rubaiyat in the terms of the 1940s."

This cut is one of many different ones in the Folkways collection, but until a copy of his script is found, Woody's Rubaiyat will remain fragmented.
