Tywoniak is shown at the Guitar Gods show playing Eddie Van Halen's cover of the Kinks song "You Really Got Me", followed by more interview footage of Green in the backyard of his home and O'Conner after he had left the school. Another montage of the fraught 80s show rehearsals with Green ranting and slamming doors, screaming "Don't fucking make mistakes! Not on 'Rebel Yell'!" Green is interviewed about his relationship with the students, and motivation. O'Conner is interviewed at an art space screen-printing T-shirts, reflecting on his time at the school.

Green gives a long pep talk about the upcoming concert at the youth hostel at which the kids are staying, followed by a trip to the festival.

Green gives a last-minute set of performance notes before they take the stage.
