FANS paying sombre tribute to the late Michael Jackson in Sydney yesterday may have felt a ghost was moonwalking among them.
A group of about 30 young people who gathered at Hyde Park at lunchtime for a memorial to the icon were treated to a performance by Sydney devotee Jason Jackson.
Jackson, 35, from Narellan Vale, whose obsession with the star fuels his career doing tribute shows, got up in front of the crowd for a speech and a few songs, his manager and mother, Theresa, by his side.
But the slight impersonator, dressed in a red blazer and black hat, did not just mimic his icon - he channelled him.
He mimed a version of Gone Too Soon to a CD track played through a portable amplifier, as bemused passers-by looked on.
The tempo then picked up with another mimed version of Billie Jean. Jackson, who changed his name by deed poll from Jason Mark Zamprogno, donned a single white glove and performed the icon's trademark crotch-thrusting and moonwalk.
The gathering had been organised by fans through Facebook. Many reunited in the afternoon for a collective moonwalk at Martin Place.
Fan Jess Bayly, 25, said she had been crying consistently since the news of Jackson's death.
"When he died, part of my childhood left," she said.
