For the purpose of being able to convincingly perform the Wonders' songs on-camera, Scott, Schaech, Zahn and Embry took several weeks of individual lessons, followed by daily practice as a group. Of the four, only Zahn and Embry had any prior experience of playing their assigned instruments. They eventually honed their performance to the point where extras on the set thought they were actually playing the songs, when in reality they were miming along to recordings by professional musicians.
