Originally posted by marik:1) you can tell from where Bono's eyes are looking, that he isn't the one playing piano. He doesnt look down, not even for a second. and you can see that his arms arent moving at all. and they would if he was playing piano. Furthermore, you can outright hear him address the piano player at 3:23 saying "and again" for another round of bars.
2) i doubt it is Edge playing piano. otherwise, he would have filled in with backing harmonies, or otherwise be addressed by Bono
And 2) Who else would it be then in these times of social distancing? And I think I can hear Edge singing a slight 2nd voice near the end as well
