Billy Corgan sings The World's Fair." Billy Corgan and his Smashing Pumpkins played to a packed Cobb Energy Centre crowd Tuesday night, April 26, 2016; Liz Phair opened the show. Though the stage was set up for his touring band, which includes original Pumpkins drummer Jimmy Chamberlin, Corgan opened the show playing solo and acoustic for the first 3 songs, which is the time allotted for photographers.
