Several thousand people won passwords via lottery so they could buy tickets but promoters say tickets will be void if the ticketholder's name doesn't match the one on the credit card used to pay for the ducets.

Some fans are furious, claiming early e-mail messages neglected to state that.

"There were no stipulations in respect of who could pay for, and thus claim, the tickets," wrote Dandu, from Canada, in an e-mail to the BBC.

A second e-mail, clarifying the terms and conditions, was apparently sent out several hours later, however, many fans had already bought tickets.

Promoter Harvey Goldsmith has defended the move, noting it was intended to deter scalpers.

Slated for Nov. 26 at London's O2 arena, the concert will mark the first time the three remaining members of Led Zeppelin will play together since 1988. Pete Townshend, Bill Wyman and Paolo Nutini will also perform at the show -- a tribute to Ahmet Ertegun, the late founder of Atlantic Records, the BBC said.
