What a great way to pay tribute to the King of Pop!
From the You Tube page:
These are two performances made at Segels Torg and the Central Station (a third installment is planned to happen at Stureplan at 23.00 tonight).
The dance collective Bounce came up with the idea and invited the public to a short choreographed session before hitting the streets.
