Harry Styles Dances Along to This One Direction Hit at Niall Horan’s Concert: Watch

Close enough — welcome back, One Direction. In a rare and exciting twist of events for fans of the boy band, both Niall Horan and Harry Styles were under the same roof singing one of their old hits, with the “As It Was” musician attending the Irish singer-songwriter’s Manchester concert Tuesday night (Aug. 27). 

In one video filmed by a fan at Horan’s Co-op Live performance, Styles — sporting a scruffy mustache and yellow cardigan — enthusiastically rocks back and forth as the The Voice alum sings 1D’s 2014 track “Stockholm Syndrome,” which the “Watermelon Sugar” musician co-wrote with three other songwriters back in the day. “Oh, baby, look what you’ve done to me,” Horan belts as Styles mouths along, waving his hands in the air. “Oh, baby, you got me tied down.” 

Horan has been performing “Stockholm Syndrome” solo on his The Show: Live on Tour trek, but it originally appeared on Four, the penultimate album released by his former boy band before the group members parted ways. The song reached No. 99 on the Billboard Hot 100, while the LP topped the Billboard 200. 

In other clips from Horan’s Manchester show, Styles dances and chats with other concertgoers while staying close to the walls of the arena, at one point swaying along to “Heartbreak Weather” from the former’s 2020 solo album of the same name. Toward the end of the show, Horan appeared to squint from the stage as he watched his ex-bandmate shake hands, give hugs and make his way out of the venue during “Slow Hands.”

Styles is just the latest special guest Horan’s tour has hosted this month, with Ed Sheeran attending his Dublin show on Aug. 23 and jumping on stage for surprise duets of “Little Things” — which the “Shape of You” artist penned for One Direction in 2012 — and “Lego House.” After the show, Sheeran shared a video on Instagram of him rehearsing the latter track with Horan.
