Well, not quite "barely". The Number Of The Beast, Run To The Hills, The Trooper, 2 Minutes To Midnight, The Evil That Men Do, Fear Of The Dark. Wasted Years might be getting there too. I'd say those are the ones that most casual listeners are familiar with. Also the ones that might be know in the "mainstream", with things like the appearance of The Trooper in the final season of Stranger Things, or many of those songs still being played on the radio in some cases. We could make a case for songs like Aces High and Wrathchild as well, but imo the previously mentioned ones are the core "classics". Basically a bunch of 80s singles, for the most part lol
But your general point stands. With TFP they showed that they are willing to ditch a lot of the expected songs. That they are willing to mix things up and go for some deep cuts. RFYL was one of their "safest" setlists, given the theme, so I could see them being much more adventurous with the next one again.
