U2's April 8 concert at Aloha Stadium and nine other dates at the end of the Grammy-winning act's Vertigo tour have been postponed, promoters announced yesterday.

Greg Terlizzi, a spokesman for Live Nation, co-promoter of the tour, said an immediate family member of someone in the band had fallen ill. He said Honolulu fans should hold on to their tickets, as the concert is expected to be rescheduled.

Reserved seating and general admission tickets purchased through Ticketmaster for the concert will be honored for any new date.

"Any fan of U2 will realize that this decision has not been taken lightly," said Arthur Fogel of tour co-promoter The Next Adventure, in a press release. "We will announce further details as soon as we have them."

The postponement affects Vertigo tour dates from March 17 through April 8 in Auckland, Melbourne, Adelaide, Sydney, Yokohama and Honolulu.

New dates for the concerts have not been announced.

Ticketmaster will accept requests for refunds, although service and mailing charges will not be credited. Ticket holders seeking refunds who purchased tickets online or by telephone through Ticketmaster should call (877) 750-4400. Refunds for tickets purchased at Ticketmaster point-of-sale box offices will be handled at the purchase locations.

The postponement of the Vertigo tour's final shows also affects the touring schedule of hip-hop star Kanye West, who was scheduled to open all U2 shows in New Zealand and Australia. In addition to those dates, West was planning his own solo concerts in both countries, Japan and Hawai'i. Tickets for an April 9 Kanye West concert at Blaisdell Arena went on sale on Saturday.

"Right now there is no plan for Kanye's show to go away because of this," said A Tom Moffatt Production Inc. general manager Barbara Saito, of West's Honolulu show. "We've not heard that (our) date has been affected at all by this."
