Russian folk and revolutionary songs

Explanation:

In the excerpt of the book, "We shall not be Moved," we learn that the picketers sang, “O Dubinushka” and “Tortured and Enslaved” as they moved through the garment district in very cold weather. "O Dubinushka" is a song that was composed by Nicolai Rimsky-Korsakov in 1905 during the Russian revolution. The title of the song in English means 'The little Oat Stick' and it tells the story of the revolution from the standpoint of a worker.

"Tortured and Enslaved" is another revolutionary song that describes the resilience of the people despite immense suffering.
