As the Mod 4 stage show grew, so did their setlist. In a 2004 interview with Mike Markesich for his book TeenBeat Mayhem!, Nellie mentions that at one point they had up to 57 different numbers in their repertoire. Examples include “Hang On Sloopy”, “White Rabbit”, “Good Lovin”, “For What It Is Worth”, “You Keep Me Hangin On”, “Sgt Pepper”, “Purple Haze” and “Respect.” In 1969 the group told the Quad City Times, “We play a lot of Aretha Franklin, Jimi Hendrix and the Beatles.”
After graduating high school, the four girls went their separate ways to attend different colleges. Officially, however, the group never broke up. They remain in contact to this day.
