Because if you had only listened to their second album, The Midnight Organ Fight, you were probably expecting a night of dark lyrics and general seriousness. And it's not that they ignored the break-up themes of Organ Fight -- they played plenty of tunes off that album quite well; it's just that the messages seemed a bit lighter in a live setting, perhaps easier to digest, especially when you're seeing how much fun Hutchison is having sing his earlier darker material.
To put it simply, this was a steady rock show. It wasn't laden with feedback or exaggeration, but Frightened Rabbit's 90-minute set flashed enough muscle to declare that these Scots won't be sinking anytime soon. No, not when you have songs like they have. And not when you have Hutchison leading the way.

You could argue that Hutchison and Co. could have played longer, but this was their first trip to St. Louis, so you could also argue that they did their job -- which was to perhaps leave the stage with their followers wanting a bit more.
The three-song encore of "Poke," which Hutchison performed solo acoustic, singing the ending unplugged with the audience, "Living in Colour," and "Keep Yourself Warm," a tune that was requested often throughout the night, left enough of a punch, though, to keep everyone in the room content -- perhaps just enough to tide them over until the next Frightened Rabbit show.
"You won't find love in a hole," Hutchison sang, as the evening drew to a close. And as a final surprise, he ended "Keep Yourself Warm" chanting "I am trying to break your heart," an obvious nod to Wilco's Jeff Tweedy, who grew up just across the river from the venue.
A simple, if not perfect, way to end things, even though he wasn't breaking any hearts.
