A huge crowd gathered in London, UK on Friday for a mass "moonwalk" — paying tribute to Michael Jackson by dancing to his most iconic songs and replicating his famous walk. The horde of people gathered on the streets outside Liverpool Street train station, one of the city’s major transport hubs, and burst out into cheers, chants and dances to the tunes of “Billie Jean,” “Bad” and “Thriller.” Life-long Jackson fan Milo Yiannopoulos organized the moonwalk, the singer’s trademark backwards shuffle, by sending messages via Twitter and Facebook.
