Corpse Revivers were a style of drink which were intended for a bit of the hair of the dog (an expression that refers to alcohol used as a treatment for a hangover). Hard to say exactly what it was about these drinks that made them seem more appropriate for this use than other drinks. This particular version isn't seen very often.
