Because after watching and obsessing over “Firework” covers frommiddle school students, high school students, college students and, duh, Glee‘sRachel Berry, another one has just surfaced. This one’s sung (not lip-synced) by the cast of the reality show The Glee Project and OMG, can these guys sing.
