The great thing about a boyband? There's plenty of coverage and you know one of them is more than happy to step in and sing one of Hazza's juicy parts.
How sick was Harry? Just a bit under-the-weather, as his voice gave out a few times. And, as we all know, that's just tragic.
At one point, the crowd was more than happy to help, as Harry took a water break during "Story of My Life" to recover. And lucky Niall got to take on Harry's part in "You & I." Juicy, indeed.
At tonight's show in Edinburgh, Harry wasn't singing to save his voice, but is he on vocal rest? Fans are understandably worried.
Hope Harry's feeling better soon!
