Coldplay [ tickets ] has canceled the remaining dates on its current U.S. outing, and has postponed one aborted date until early April. Two of the group’s members have been felled by the flu.

The group’s Feb. 16 set at New York City’s Irving Plaza ended after two songs due to frontman Chris Martin’s and bassist Guy Berryman’s bout with the illness. That show has been postponed until April 9, at which time it will take place at New York’s Roseland Ballroom, according to the group’s website. Tickets to the original show will be honored on April 9.

The Feb. 17 performance in Boston was subsequently canceled, but the group plowed through a Feb. 19 performance in Chicago.

“It was felt that this gig could be done as a final push,” wrote band manager Phil Harvey of the Chicago date in a message posted on the group’s official website.

The final two shows on the tour--set for Tuesday night (2/20) at Guvernment in Toronto and Friday night (2/23) at the Hard Rock Café in Miami--have also been canceled, as the band plans to return to its native England on Tuesday (2/20), according to Harvey’s message.

Ticket refunds for all three of the canceled shows are available at the point of purchase, according to Coldplay [ tickets ]’s website.

Harvey’s message indicates that the group is planning an extensive North American outing for May and June.

Coldplay’s North American tour began on Feb. 8. The Brit-rock quartet was touring in support of its U.S. debut, “Parachutes” (Nettwerk/Capitol).
