A video released Thursday showed Michael Jackson vigorously practicing a song-and-dance routine days before his death, supporting accounts he had been in good health.

In footage obtained by AFP, the pop legend performed at the Staples Center in Los Angeles on June 23, two days before he died, as he prepared for a 50-date set in London starting in July.

Jackson, while thin, is seen dancing with energy in a tightly choreographed sequence with a group of performers. Jackson sings on a headset and at one point pushes back his jacket to reveal his red shirt underneath.

In the footage, Jackson switches sharply in styles in a medley of some of his hits. The video starts with Jackson dancing wildly in front of a rock 'n' roll guitarist before a pause for dramatic effect.

Jackson then shifts to a snippet of "Billie Jean," one of his greatest hits, before singing, "They Don't Care About Us," one of his most controversial tracks in which he brought in a hip-hop influence.

The set ends with a sample of a car horn. The stage then fades to black as an outside voice instructs, "Hold for applause."

Associates of Jackson have described the 50-year-old pop star as being in good form, including at another rehearsal just hours before his death.

Jackson collapsed and died on June 25 at his rented Los Angeles mansion. Speculation has focused on whether Jackson was taking painkillers or other medication.
