Denny, a former member of the Crooning Crab Cakes glee club at Springfield High School, grabs the spotlight as Eugene struggles to keep up with him.
Trouble comes in the form of Lois Franklin, "Big" Earl's daughter, who shows up to help Duke evaluate the group, but who also broke Eugene's heart many years before.
After hearing Duke sing ("Fools Fall in Love"), the boys welcome him into the group and Lois realizes her budding romantic feelings for him.
The finale sequence features Denny & The Dreamers returning from their triumphant world tour ("Pretty Little Angel Eyes"), and the quartet becomes a quintet as Lois joins them onstage in a doo-wop finale extravaganza ("Do You Love Me/The Twist"/“Rama lama ding dong"/Unchained Melody (Reprise)").
