The guys, fresh off their appearance on SNL over the weekend, have released a preview clip from One Direction: The TV Special that seems aimed at the old school 1D fans, as it's the boys performing their 2012 hit "Little Things."

The track gets proper singalong treatment from the crowd, in its subdued style. And you can only view it online, as the special's co-director revealed on Twitter that it "isn't on the show but gives you a taster."
