Jackson Tour Minus One Brother

July 24 -- The planned reunion of the Jackson brothers, their first since 1984's Victory album and tour, is minus one Jackson.

A reunion of all six Jackson brothers had been billed as a highlight of two all-star concerts slated for September at New York City's Madison Square Garden to celebrate Michael Jackson's 30 years as a solo artist.

It looks like Jermaine is out in the cold after an open letter attributed to him and brother Randy raised objections to "exorbitant ticket prices" being charged for the shows and to plans for the Jacksons to share the stage with other performers during their reunion.

On Friday, the producer of the shows, David Gest, issued a statement excluding Jermaine Jackson from the talent lineup and leaving unclear the status of Randy, the only one of the brothers who was not a member of the original Jackson 5.

On Monday, another statement followed, this one attributed to Marlon Jackson, saying Randy was still on for the reunion but that Jermaine would not appear.

"I am very sorry for the confusion my brother Jermaine has caused by his statement," Marlon wrote, adding, "We wish Jermaine all the best on his solo career."

A spokeswoman for the producers said Monday that Gest "only wanted people [in the show] who are happy doing it" and that he "interpreted" Jermaine's remarks in the memo to mean that he "did not want to participate in the event."

Jermaine split from the group in 1975 when the other four members of the original act left Motown and signed with Epic. He was replaced by Randy and the group's name was then changed to the Jacksons. Jermaine rejoined his brothers at Epic in 1984 for Victory.
