It's been 10 years since Jack Black assembled a group of prep school kids into a kick-ass rock 'n roll band in "School of Rock."

To celebrate, Black and several of the film's children — now all grown up — played a reunion concert. And there's video, albeit brief.

Miranda Cosgrove (Summer), Joey Gaydos Jr. (Zack), Robert Tsai (Lawrence), Kevin Alexander Clark (Freddie) and Rebecca Brown (Katie) joined their one-time fictional teacher on stage.

Director Richard Linklater and writer/co-star Mike White were also in attendance. Technically, the 10th anniversary of the film's release will be Oct. 3, but we'll let that slide.
