Last night, part of the cast of the majorly Tony-winning musical "Once" trooped over to the "America's Got Talent" set, where they filled up the window of time when AGT competitors were anxiously waiting to hear whether they were in or out, with a song. It was both a cruel stalling mechanism and also pretty great! Because the song Tony-winner Steve Kazee, Tony-nominee Cristin Milioti and the vaguely Irish seeming ensemble performed for all of talented America to see was "Falling Slowly," the Glen Hansard/Marketa Irglova original you might remember if you saw "Once" the movie (it won the Oscar that year for best song). Once you get through the Folger's commercial intro, the real stuff starts. Just try not to feel your heart soar a liiiiittle bit.
