Oh tidings of madness and woe. Gather 'round the Necronomicon, little cultists, and let's all sing these beloved holiday odes to Elder Gods. All the classics are here: "I Saw Mommy Kissing Yog-Sothoth," "Freddy the Red-Brained Mi-Go," "All I Want for Solstice is my Sanity," and "Awake Ye Scary Old Ones." And who can ever forget that rubber-room holiday favorite "Away in a Madhouse?"
These songs were all created by members of the H.P. Lovecraft Historical Society. You can hear more via this YouTube link.
