LOS ANGELES — There were fedoras and single white gloves and sequined military jackets. There was lots of moonwalking. Four people danced the choreography of “Smooth Criminal” in perfect sync.

Five dozen Michael Jackson superfans from around the world had come to a gaming arcade on Hollywood Boulevard on Monday, the beginning of two days of dancing, singing and prayers in honor of their hero.

Some remembered singing “A-B-C-1-2-3” as children; others listened to “Thriller” well into their 50s and 60s, but the one who stole the show was just an infant when Jackson died: a 10-year-old boy named Rudey Parra who glided across the arcade floor in his loafers and white glove, a flawless re-creation of moves he’d studied on YouTube. Another dancer, Gowardy Horton, 38, gave Rudey his fedora, crowning him the party’s reigning Michael.
