I saw Ghost live a couple times during the Cardial Copia era. I like his personality. Always a lot of naughty humor mixed into the performance.
The changing of the character is sort of a big deal for the lore of the band. So it's pretty interesting that Copia's ascension to Papa happened at a random concert, without any announcement ahead of time. Imagine being at that show, and getting to witness that unique moment. A special memory, just for the people in the room that night.
