Is the original lineup of Smashing Pumpkins getting back together? Billy Corgan posted a photo on Instagram of him, guitarist James Iha and drummer Jimmy Chamberlain hanging out in a studio. The only person that was missing was original SP bassist D’Arcy Wretzky. The last time the original lineup played together was 1999, and recently Billy and James buried the hatchet and played some live shows together. Word is Billy is back in touch with D’Arcy as well, does this mean a reunion is on the cards in 2018?
