In a masterful feat of googling with minimal information, I found the song Glen Hansard and Marketa Irglova and the Frames closed their gig with- and no, I didn’t find a set list. I remembered the song was by someone named Mick and that it had the word day in it. Search string: Mick, days, lyric, song. So here they are, at Bonnaroo last year, singing Mic Christopher’s Heyday.
