In terms of rarities it depends on the tour - e.g. I saw 40 on the last tour but that was an expected song at my early U2 shows. Back in the 80s the setlists were fairly standard but a few covers were thrown in from TJT tour, so I heard Maggie’s Farm, C’mon Everybody and Springhill Mining Disaster. In the 90s I heard Dancing Queen, Zooropa and Babyface. In the 00’s Wake Up Dead Man, Gone and Who’s Gonna Ride Your Wild Horses.
