I wouldn't have minded them dropping it, but I like "Workin' Them Angels" a lot, and thought it came across pretty well live on both legs in '07 and '08, so I can't fault them for that choice. I figured it would be one of the S&A songs that would survive this tour.
I think "Armor and Sword" is a much better song, but it loses something live, as there are too many guitar things going on for Alex to do them all live and to give the song the power and charm it needs.
