The Casanova Club was a nightclub owned by Alex Logue in 1970s Newcastle, England. It is known as the first venue for young John Constantine's punk rock band Mucous Membrane. Alex Logue had developed a reputation for himself as a sex and drugs magician, and after shows, he would often invite guests and performers down into the club's cellar for private parties. Dubbed the "Chapel", the cellar of the Casanova Club was the scene of various black magic occult ceremonies and tantric sex rituals.
