CARDIFF, Wales - Participants in a tribute concert for Michael Jackson are urging fans to focus on the late star's music rather than his death.

The 50-thousand-strong crowd at Millennium Stadium In Cardiff, Wales, did just that yesterday, roaring with approval as Jackson's brothers Marlon, Tito and Jackie -- three-fifths of the original Jackson 5 -- took the stage to perform "Blame It On the Boogie" with British boyband JLS.

On a stage shaped like a giant glove, musicians including Christina Aguilera, Gladys Knight and Cee Lo Green performed songs from throughout the King of Pop's career.

Jackson's children were also there to celebrate their late father's legacy.

The run-up to the "Michael Forever" concert was overshadowed by the Los Angeles manslaughter trial of Jackson's doctor, and marred by fan criticism, sluggish ticket sales and dissension within the Jackson family.

But once the four-hour show started, Jackson's musical genius, and the warm tributes of friends and family, carried the night.
