Dennis Flemion (June 6, 1955 – July 7, 2012) was a founding member, with his younger brother Jimmy, of the controversial independent rock band the Frogs. He was the primary percussionist for the band and was also a temporary member of the Smashing Pumpkins from 1996 to 1997, filling in on live keyboards following the death of Jonathan Melvoin. The Flemion brothers also appeared on "Medellia of the Gray Skies" on the band's single for "Tonight, Tonight". On Adore, the brothers backed vocals for "To Sheila" and "Behold! The Night-Mare".
