The Church of Gozer Songbook is a Cursed Artifact found in the Lost Island Rising level of Ghostbusters: The Video Game (Realistic Versions). This songbook possesses all the different worship/chorus songs that were actually the updated ancient Sumerian droning rituals, and it was belonged to the Dark Church of Gozer, one of the sects of the Cult of Gozer themselves.
A dirge-like chanting rises quietly from this dark book.
c. 1919 Having resuscitated the Dark Church of Gozer and wanting to increase its popular appeal, Ivo Shandor made attempts at updating ancient Sumerian droning rituals to modern-day worship songs into the book. The practice of singing in the Dark Church was abandoned soon afterward.
