Reschedule dates previously postponed.

U2 has rescheduled a host of dates in Australia, New Zealand and Japan that were postponed this spring due to an unidentified serious illness within the immediate family of a band member. Pearl Jam and Kanye West will share support duties at the shows, which get underway Nov. 24 in Auckland.

West, who was scheduled to open the Australia and New Zealand shows the first time around, will fill that role for all the make-up dates in those territories. Pearl Jam will join U2 Dec. 9 in Honolulu, marking the first time the bands have shared a stage since 1993. That gig will also feature a set by U2 stage manager Rocco Reedy's band Rocco and the Devils.

Ticketholders for the original Australia, New Zealand and Hawaii shows are being asked to retain their tickets, as they will be valid for the new dates.

The band was unable to reschedule a planned show in Yokohama, Japan, so has instead confirmed a Nov. 29-30, Dec. 4 run at Tokyo's Saitama Super Arena. Fans with tickets for the Yokohama show will be eligible for a special pre-sale for the makeup dates.

As it stands now, U2's Vertigo tour is the top-grossing tour in history at more than $333 million, which bests the Stones' $320 million Voodoo Lounge tour. The Stones' A Bigger Bang tour, however, is expected to top $400 million by the time it wraps in September.
