I heard it and it was like, nostalgia! The voice was pretty much immediately recognizable to me as the same front man from The Format. In late high school/early college, I was much more into music + concerts than I am now and The Format, a local band, was one of my favorites. Greg and I saw several of their concerts when they played in the Tucson or Phoenix areas.
A co-worker told me a year or two ago that The Format had split and the front man, Nate Ruess, had gone on to join a band call Fun. I didn't put any effort into looking into it, but I liked this song when I heard it last night and it's been stuck in my head. Nate Ruess has a great voice, of which the ultimate test, in my opinion, is being able to sound as good as or better when singing acoustic (such as here and here) or live.
Back when The Format were still together, they played acoustic versions of Movin' Out, Wild World, and I'm Only Sleeping, which I was such a fan of that I burned them onto a CD that perpetually lives in my car. Although I listen to the radio most of the time, I occasionally bust out my Format mix CD and listen to them.
