LONDON (AP) — Oasis Fans seeking tickets for the band’s reunion tour were faced with hours of waiting and in some cases disappointment as online platforms were unable to cope with the demand from hundreds of thousands of fans on Saturday.

The Britpop-era giant, led by brothers Noel and Liam Gallagher, is expected to play 17 shows. first shows in 15 years — in Cardiff, Manchester, London, Edinburgh and Dublin from July 4.

More than 1 million tickets went on sale on Saturday morning, with prices starting at around £74 (just under $100).

Some people trying to access the few recognised sales sites, including Ticketmaster and Gigs and Tours, were met with error messages, while many others were told they were in a long queue.

Josh Jeffery, a videographer who lives near Edinburgh, spent hours waiting in the online ticket queue before “the whole site collapsed” at the final step.

“I gave up, my friends gave up,” said Jeffery, who first saw Oasis in Manchester as a teenager in 1996. “We just decided it was too much hassle.

“While I was standing in line, I heard ‘Wonderwall’ blaring from my neighbor’s house,” he added mournfully. “He had clearly bought tickets.”

Some fans managed to buy tickets through a pre-sale lottery on Friday. Barista Isabelle Doyle said she was “over the moon” after bagging two seats for one of the band’s shows in London.

“I’ve been an Oasis fan for about 10 years now, literally since I was 11,” the 21-year-old said. “Finally to be able to see them after they helped me through my life as a teenager, it’s absolutely amazing and I’m so excited.”

Within hours, tickets were being offered on resale websites for prices as high as £6,000 ($7,800).

Oasis issued a warning, saying tickets could only be resold at face value through authorised sites.

“Tickets appearing on other secondary ticketing sites are either counterfeit or are being cancelled by the promoters,” a statement said.

Formed in Manchester in 1991, Oasis were one of the dominant British acts of the 1990s. The band produced hits such as ‘Wonderwall’ and ‘Don’t Look Back in Anger’. Their sound was fueled by sing-along rock choruses and the flammable chemistry between guitarist-songwriter Noel Gallagher and singer-brother Liam.

Oasis split in 2009, with Noel Gallagher leaving the band after a backstage altercation with his brother at a festival near Paris. Although the Gallagher brothers, now 57 and 51, have not performed together since, they both regularly play Oasis songs during their solo performances. They have also both criticized each other in the press.

When announcing the reunion, the band said fans would experience “the spark and intensity” that only comes when they share the stage together.

The tour kicks off at Principality Stadium on 4 and 5 July. Oasis will also play Manchester’s Heaton Park on 11, 12, 16, 19 and 20 July; London’s Wembley Stadium on 25, 26 and 30 July and 2 and 3 August; Edinburgh’s Murrayfield Stadium on 8, 9 and 12 August; and Dublin’s Croke Park on 16 and 17 August.

Prices for the concerts in London, Cardiff and Edinburgh range from around £74 ($97) to just over £200 ($260) for seats and around £150 (around $200) for standing. In Manchester, the cheapest tickets are £148 ($195) for standing, with no seating option.

The most expensive option is a £506 ($666) package for the London concerts, which includes a pre-show party, entry to an Oasis exhibition, souvenirs and a “premium collectible”.

Tickets for the Dublin shows start at €86.50 ($96) plus booking fees.

Alice Enders, head of research at media consultancy Enders Analysis, said that touring is now the main source of income for many musicians, and that Oasis can expect a big payday. However, the tour, which is limited to the UK and Ireland for now, pales in comparison to global behemoths such as Taylor Swift’s Eras tour.

She said Oasis needed to play catch-up in a live music market that has seen “a relentless rise in spending, consumer spending and demand for festivals”.

“It’s been 15 years since they missed a megatrend, in fact,” Enders said. “So it’s good that they’re jumping on it now. … If they wait too long, they’re just a bunch of old farts.”

The host cities expect an economic boost for hotels, bars, restaurants and shops, especially Manchester, the band’s hometown and a city renowned for its musical heritage.

Sacha Lord, Manchester’s official night-time economy adviser, said there was “a lot of interest” in the city for the reunion.

“This is a homecoming concert,” he said. “When they’re on that stage for the first time, it’s a really special moment.”
