[bratty_]

They really styled those babies so stinkin cute at the start.

[yoavry]

Their choreography for this is so like teen heartthrob omg I was squeaking the whole time like I’ve never seen it before AHHHH. Gawd, I miss them and I miss Liam so much. Love you Payno❤

[mayastylinson]

[JoaoGabriel-eksb]

Zayn poking Harry lol. Kinda forgot how deep Harry's voice was already back in 2012.

Omg. Baby Liam, BABY Zayn and Baby Harry looks like he's only 13 years old. It's shocking just how young these guys were when they started in 1D.

[gzhdiamond]

Omg, first time seeing this and they showed out‼🔥👑👑👑👑👑 Sad part is they seemed happier then before their management wore them out 😕🙁

They performed well considering there was
at least one, if not two, of them clearly having an issue with his in-ears. From the start Louis had problems, desperately trying to correct the issue, trying what he could with his receiver. He resorted to taking them out when it came to his solo. Why did the sound tech not pick up on this? Niall also had issues, he took out his right ear. Poor Harry was struggling, voice hoarse (for him) & deeper than it ordinarily was then, possibly, considering the time of year, his hay fever was affecting him. I think they were quite let down & really battled on like the pro’s they were. Well done in spite of the gremlins.
