The timeline runs through the "Up All Night" tour and takes you "behind the lyrics" of "What Makes You Beautiful," with songwriter Savan Kotecha describing the pressure to deliver a hit and how he had no lyrical thoughts until his wife's "feel so ugly" comment turned into the spark of an idea ("she doesn't even know how beautiful she is.")
There are director's notes from Vaughan Arnell of what it was like to shoot the high-energy video for "Live While We're Young" from the band's second album, Take Me Home, audio of the fellas talking about wishing they could time travel to see the dinosaurs and pictures, so many pictures. Plus, hidden phone numbers with silly bits of audio from the guys, band member spotlights on each and behind-the-scenes pics from the silly "Best Song Ever" shoot from their third album, Midnight Memories.
