LONDON -- For Herve Tram, being a Taylor Swift fan isn’t just about the music.

The 28-year-old computer network engineer from Paris identifies with the community of Swifties, as they are known. When the pop star's performances in Vienna were canceled last week due to a security threat, Tram took a small, personal initiative: He gave away two extra tickets to her upcoming shows in London to fans who missed their chance to see their idol in the Austrian capital.

“That’s the strength of this fandom,’’ Tram said. “We support (out) for each other.’’

The devoted group of Swift fans, who have packed stadiums worldwide to witness the 3 1/2-hour spectacles on her Eras Tour and belt out the lyrics they know by heart, have been taken aback in recent days.

Firstly, a knife-wielding attacker took the lives of three young girls during a Swift-themed dance class in northern England, triggering a week of anti-immigrant unrest across the U.K. after right-wing activists spread false information about the assailant. Then, performances in Vienna were cancelled after police apprehended three individuals inspired by the Islamic State who they believed were planning to attack the concert venue.

Despite these events, fans remain enthusiastic to see Swift perform during five shows from Thursday to Tuesday at London's Wembley Stadium, concluding the European leg of the Eras Tour. Fans are eager to wear Swift-inspired outfits, exchange handmade friendship bracelets, and, of course, dance.

Take Meagan Berneaud, 30, from Columbus, Ohio, who has been a devoted Swift fan since she was 13.

Berneaud had some doubts about traveling to London after recent events reminded her of the 2 1/2 hours she spent under lockdown during a 2016 terror attack at Ohio State University. However, she decided to go and even created a thread on X, formerly known as Twitter, to connect fans who missed the Vienna shows with those willing to sell or give away tickets to the London concerts. She’s had over 3,000 views.

“I just have to remind myself not to be afraid,’’ she said. “I have to trust ... that law enforcement is doing everything they can to keep us safe.’’

Some fans who had planned to attend the show in Vienna were determined to overcome their anxieties and try to see another performance, inspired by Swift’s song, “Fearless.″

"And I don’t know why.

But with you I’d dance in a storm.

In my best dress.

Fearless."

It's a number she sings with passion, while twirling and swirling in an array of sparkly dresses in the song's music video.

Presila Koleva, 26, a design engineer from Cambridge, England, had been eagerly anticipating seeing Swift in Vienna for over a year. She even purchased a green dress similar to one Swift wears during the Folklore set on the Eras tour and made 30 bracelets to exchange with other fans. She was heartbroken when the shows were called off.

But then she connected with Tram, who gave her one of his tickets. Now, that dress will be worn.

“There (are) kindhearted individuals who will extend a helping hand to a stranger they don't know, simply because they have witnessed the terrible ordeal they've been through,’’ she said. “It could have ended much worse.’’

The fervor of Swift’s fans and a set list that encompasses over 40 songs spanning all stages of her career have contributed to the Eras Tour becoming the highest-grossing tour of all time, generating over $1 billion in ticket sales last year, according to Pollstar Boxoffice, a data collector for the live music industry. The tour is projected to surpass $2 billion in revenue before it wraps up later this year in Indianapolis.

The demand for the London concerts remains strong, with ticket prices reaching thousands of pounds on unauthorized resale platforms.

With Swift’s tour concluding in Europe and a large contingent of youthful fans who have flexible schedules, particularly during the summer months, the recent events are unlikely to negatively impact the demand for tickets to the London shows, according to Rafi Mohammed, an expert in pricing strategies and founder of the Cambridge, Massachusetts-based consulting firm, Culture of Profit.

“If anything, the three sold-out concerts in Vienna that were canceled will likely lead to even higher demand,” he stated.

Even so, security is a concern.

London’s Metropolitan Police Service has attempted to provide reassurance, pointing out that it has learned from the 2017 attack on an Ariana Grande concert at Manchester Arena that resulted in the deaths of 22 people and injuries to hundreds more.

Organizers have pledged “additional ticket checks" at the 90,000-seat Wembley Stadium, which prohibits concert goers from bringing anything significantly larger than a small bag into the venue. Those without tickets will be directed away from the stadium.

“London is a large city. We’re accustomed to hosting all of these events,’’ said Tracy Halliwell, the head of tourism for Visit London. “You’ll see an increased police presence on the ground, which is simply to ensure that everything … runs smoothly.”

For his part, Tram is concentrating on what the fans can do, recalling how Parisians responded after the attack on the Bataclan theater in 2015 to show that terror would not prevail.

“We saw hundreds of thousands of people take to the streets to show they are not afraid, and I believe we (will) also see that in London,” he said. “Fans will demonstrate they are not afraid. And as Taylor said, we are fearless.”
