It was played maybe every other show in 2011 and 2012 - when I started following their sets - which seemed a little more reasonable for such a song (i.e., a song that wasn't a single or on the greatest hits package).
I think Porch would work nicely closer to the start of the show. I presume it's a good, lengthy song that not only allows MM to show off his skills but gives EV's voice an extended break that isn't part of the encore.
