• The production featured extensive aerial work and large moving props, highlighted by a mechanical butterfly that carried her over the audience.
• A figure‑of‑eight stage and rapid‑fire costume changes framed a set that blended new 143 material with crowd‑pleasing singles like California Gurls, Teenage Dream and I Kissed a Girl.
• Reviews from The Times and The Guardian praised the ambition and crowd reaction but said the heavy visuals and narrative often distracted from the songs.
• Perry nodded to recent scrutiny with onstage remarks and a lyric tweak about wanting to ditch social media, and she brought fans onstage for interactive moments.
