In 1996, the brothers toured with The Smashing Pumpkins on the Mellon Collie and the Infinite Sadness Tour. During the encores of "1979", Jimmy, clad with a silver bat-winged suit, would pick members of the audience to dance onstage.
The brothers Flemion also appeared on the Pumpkins' "Medellia of the Gray Skies" on the band's single, Tonight, Tonight. On Adore, the brothers backed vocals for "To Sheila" and "Behold! The Night-Mare".
