James Morrison originally wrote "So Beautiful" with Take That's Gary Barlow in the late 2000s. He didn't record it at the time as he felt it too cheesy. However after his relationship with long-term partner Gill re-ignited after a difficult period, the song took on a new context, and seemed to sum up everything they'd been through. So he recorded it for You're Stronger Than You Know.
Ronnie Van Zant wrote the Lynyrd Skynyrd classic "Gimme Three Steps" after making the mistake of dancing with a girl whose boyfriend was in the bar and probably had a gun. He asked for a 3-step head start.
