Billy Corgan made a folk album signed "William", and it makes sense

"'Cotillions' is basically Billy making his version of a folk/country/Americana album, and at this point in his career, it’s more exciting to hear him do this than rehash '90s Smashing Pumpkins songs... It’s one of the few times in his career that he didn’t make a lofty, ambitious album. It turns out Billy Corgan can be pretty good when he reels it in, too" - Brooklyn Vegan says quite fondly about Smashing Pumpkins frontman's solo album. It's signed with his full name - William Patrick Corgan.
