Answer
Contrary to popular belief, Billy Corgan has never been referred to as "The Pumpkin King." This moniker is associated with the fictional character Jack Skellington from Tim Burton's "The Nightmare Before Christmas." Corgan is widely known by his stage name, William Patrick Corgan, Jr., and has been the lead vocalist, guitarist, and primary songwriter of the alternative rock band The Smashing Pumpkins since their formation in 1988.
