According to Setlist.fm (so take this with a grain of salt), In These Arms was sung by David Bryan!

I honestly think this set is a small step up from Europe. WLOL was performed much later in the set than usual, so theoretically it wouldn't have dulled the mood as much as it would in slot 3 or 4 (though I still wish Jon would permanently drop it from live shows). If David did sing ITA, that would give Jon a nice break mid-show and hopefully allow him to go a bit longer, hence the 20-song main set. WGIGO, ILTT, and Captain Crash were all absent from this set as well. I still think Scars, Labor of Love, Real Love, I Will Drive You Home, Diamond Ring, Never Say Goodbye, acoustic Superman Tonight, or even The Fighter would be better choices than Amen for the slot between KTF and BOR. I probably would've also swapped Wanted and WDR so Jon's voice would be slightly stronger on the former.
