You may or may not have heard: a fan called Jonathan held up a sign asking to play piano on Stay three consecutive nights, Milwaukee, Indy and finally on 5/12, the first night at the United Center in Chicago. Bono asked Jonathan if he played well. He then asked Jonathan what key it was in. He answered E-Flat. Bono turned to Edge who confirmed. Bono then said “Come on up”. Jonathan did a great job.
