A year ago, DJ John Quick was scheduled to spin at a party when he got the news - Michael Jackson was dead.
So instead of playing the hits of the moment, the Harlem event turned into an impromptu tribute to the King of Pop.
"It was the first time I've ever seen grown people crying and dancing at the same time," he said.
Today, the first anniversary of Jackson's death, Quick will once again play Michael Jackson tunes, at the club Taj in Manhattan, but he expects a more cheerful party this time.
It will be part of the global celebration of Jackson's life. Jackson died at age 50 as he was preparing for comeback concerts in London.
In that city, a memorial was unveiled Thursday to reporters who packed the foyer of London's Lyric Theatre, the site of an impromptu wake after the superstar died last year.
While celebrations are expected today, there will also be somber remembrances. In Gary, Ind., Jackson's hometown, there will be a tribute at the Jackson home. City officials said they expected Michael's mother, Katherine, and his niece Genevieve to show up, along with thousands of others.
Fans are also expected to gather at Forest Lawn cemetery outside Los Angeles, where he is buried.
Katherine Jackson has thrown her support behind a "Forever Michael" fan event to be held Saturday at the Beverly Hilton in Los Angeles. Tickets range from $150 to $500.
The Apollo Theatre in Harlem, where a young Michael Jackson and his brothers won amateur night, will host a commemoration today of Jackson's life in front of the recently installed plaque honoring him in the legendary theater's new hall of fame.
And later in the afternoon in Harlem, around the hour of Jackson's death, the Rev. Al Sharpton and his National Action Network will hold a moment of silence.
