Thousands of Led Zeppelin fans have been notified they were successful in the ticket lottery for the rock band's one-off reunion concert.
The surviving band members have not played together for 19 years
Tickets for the show, on 26 November at London's O2 arena, cost £125 each, plus booking fee.
"Much to my surprise, I'm one of the lucky ones," fan Padraic Conway wrote to the BBC News website. "I'm stunned!"
But many were left disappointed - more than one million people had applied for the 20,000 tickets.
According to fans who emailed the BBC, all tickets will have to be picked up in person from the O2 arena. Fans will also be given a wristband which must not be removed before the concert.
The tickets and wristbands will only be available for collection on 25 and 26 November.
The move is likely to be a further attempt to combat touts. On eBay, some lucky applicants are attempting to sell their passwords for the official ticket sale - charging up to £1,000 a time.
Led Zeppelin have sold more than 100 million albums in the US alone
But promoter Harvey Goldsmith has said the password must match the personal details of the person who applied - otherwise the tickets will be cancelled.
"Unfortunately, a small number of unscrupulous people have decided to take advantage of the fact that they had been awarded the opportunity to purchase tickets," he said.
"It is even more unfortunate that eBay and a number of ticket scalping sites have chosen to take advantage of this situation.
"Please note that unless the ticket, the code and correct identification match, those tickets will be invalid. Anyone who chooses to purchase tickets in this way will lose their money."
Led Zeppelin fan Nader, who contacted the BBC, said he had spent £277 to buy two standing tickets.
"But, you know what? It's worth it," he wrote. "Once in a lifetime. I cannot wait!"
Pete Townshend, Bill Wyman and Paolo Nutini will also perform at the concert, which is a tribute to Ahmet Ertegun, the late founder of Atlantic Records.
Led Zeppelin's last full concert was in Berlin in July 1980, two months before the death of drummer John Bonham.
A show to celebrate the 40th anniversary of Atlantic Records in 1988 was the last time singer Robert Plant, guitarist Jimmy Page and bassist John Paul Jones all played together.
But a rift between Jones and the other two band members opened after Page and Plant started working together without him in the 1990s.
Proceeds from the show will go to an education fund set up in Mr Ertegun's memory.
