Throughout the show, fans shook lightsticks, parroted Katseye’s dance moves and, in some cases, spontaneously burst into tears.
Many concert-goers also wore bindis, inspired by Lara, who has proudly incorporated her Asian heritage into her aesthetic.
One individual also came dressed as a courgette, a reference to Internet Girl’s so-weird-it-almost-works refrain, “Eat zucchini”.
The energy was infectious. And, if you looked closely, the parents were enjoying the show as much as their kids.
Even Spice Girl Melanie C is a fan, hosting a Q&A with the band during their first UK trip last October.
“They’re incredible girls,” she told the earlier this summer. “They’ve got great music, they’ve got a great work ethic, and they’re really beautiful, you know?
“Obviously, they’ve had a little drama, as happens with all bands, but they work so goddamn hard.”
