Translated from Italian, the new singer reveals, "“I am Papa Emeritus Zero. The party is over and now a new era begins. The Middle Ages begin now."
From Blabbermouth
Papa was forcibly removed from the stage by two men during the band's closing number, "Monstrance Clock", A short time later, a very elderly man wearing a white and gold version of Papa's robes and his signature make-up took the stage and addressed the crowd, saying in Italian, "I am Papa Emeritus Zero. The party is over and now a new era begins. The Middle Ages begin now."
The band posted footage of the incident to its official Instagram account but has yet to comment on the matter. It appears, however, that the reign of Papa III has ended.
Of course, all this is part of a big inside joke: the band supposedly dismisses the old Papa and recruits a new one on every LP, but they are all the same person — founder Tobias Forge, who will no doubt perform as a new Papa Emeritus on the next album cycle.
