We’re about 20 feet away from the doors of Stage 29 on the Warner Bros. lot that we start to hear the screams. We’re late — a 6:30 check-in time does not generally agree with Los Angeles rush-hour traffic — and the live finale of Season 7 of America’s Best Dance Crew begins at 7 p.m. on the dot. “This is live TV people, live TV!” stagehands bark as they usher the few remaining stragglers into the sound stage — barely allowing a millisecond to stop and take a phone pic of producer Randy Jackson, who’s still hanging outside with his posse. (The show’s full title is Randy Jackson Presents America’s Best Dance Crew, which makes it pretty troublesome to tag on Facebook.)

Oh right — some background: Randy Jackson Presents America’s Best Dance Crew is a reality dance competition show on MTV, and last night it crowned Arizona underdogs Elektrolytes as its Season 7 winners.
