Via Wikipedia:
"Shub-Niggurath, often associated with the phrase “The Black Goat of the Woods with a Thousand Young”, is a deity in the Cthulhu Mythos of H. P. Lovecraft. The creature is sometimes referred to as “The Black Ram of The Forest with a Thousand Ewes,” lending a male gender to the entity that is often thought of as female."
Given that tMG have other Lovecraft-related songs, it doesn't seem out of the realm of possibility that the "Young Thousands" might be referencing big Shub, or at least inspired by it.
Anyone know if it's been confirmed or denied that there is a connection?
Thanks,
