One Direction popped into the BBC Radio 1 Live Lounge and delivered some pretty flawless performances, including one oldie-but-goodie - a cover of "Torn." They really brought things full circle, with all the 1D X Factor fetus nostalgia flooding back.
In addition to their own tunes and the "Torn" cover, they also brought their A game with a "FourFiveSeconds" cover. So. Good.
