The annual Waa-Mu show is the largest student-written musical in the country. This year’s production, “Waa-Mu: Off The Map,” is about NU students who travel to New Orleans for one last adventure together after a stressful Winter Quarter. Waa-Mu is a student-led production and is headed this year by three co-chairs: Jon Harrison, Rachel Shapiro and Patrick Sulken. Jon, Rachel and Patrick took some time during a break in rehearsals to chat with The Current about their roles as co-chairs, Rebecca Black and their favorite moments from “Off The Map.”
