Today, I learned that there is a Lovecraft-inspired Fiddler on the Roof parody-musical entitled
A Shoggoth on the Roof. Published by the H. P. Lovecraft Historical Society, it is credited to a member of the society who is referred to only as "He Who (for legal reasons) Must Not Be Named".
The songs have been recorded.
They're on YouTube.
EDIT: OH WOW
Does anyone make fishmen in dancing poses?
