Go to the scene where they are competing in the state choir contest. You see that when Lauryn Hill

is singing, the piano player is also wearing a robe. But when they take off their robes before coming on stage, you don't never see the piano player pull his off. Yet, we they go to him after

everyone takes off their robes, he doesn't have his on. He couldn't have taken it off and kept playing.

You also see that the lead singers have to use mics so everyone can hear them in the building. The two rappers and Lauyrn Hill at the beginning use them, but when she and Ahmad sings, they don't use a mic for the rest of the song.
