During the three-months shooting period nearly 30 hours of footage were filmed. Additionally, five cameras shot the entire concert performance simultaneously which resulted in another 10 hours of footage. The first rough cut of the film ran 5 hours and was subsequently cut down to 2 1/2 hours. The final cut runs 86 minutes.
In an early post production stage the filmmakers intended to include a voice-over narration throughout the entire film which would have illustrated the events from the filmmakers' view. However, as it was realized that the film's protagonists tell much of the story themselves, the idea was dropped. Eventually no voice-over narration was scripted nor recorded.
