In "Beasts of England," from Animal Farm, what and where is the potential foreshadowing for the story?

The main example of foreshadowing in "Beasts of England" is found in the lines "Soon or late the day is coming/Tyrant Man shall be o’erthrown..." (12). This foreshadows the events that occur on Manor Farm, as the animals rise up, drive Mr. Jones from the farm, and take it over, renaming it Animal Farm. The rest of the song could only be understood as foreshadowing in an ironic way. The song speaks of "riches more than mind can picture" and "freedom" for the animals, and of course none of these things happen (13). Rather, the animals find that the pigs, under Napoleon's leadership, become every bit as exploitative and cruel as Jones and the humans. Man is overthrown on Animal Farm, only to be replaced by pigs. So most of "Beasts of England" does not come true, and in fact, the pigs will later ban the other animals from singing it.
