It's the track the band arrive on stage to every night and for the third show in London Patti Smith was in the house to take on the vocals.
Here's the NME report - which also quotes Noel Gallagher, reflecting on joining the band onstage on Monday for 'Still Haven't Found: "It was a dream come true..."
Couldn't put it better than JoshTheTree it in our comments section, 'After the euphoria of Monday how could U2 top the last show? With New Year's Day, Gloria and Bad and bringing out Patti Smith. How cool was that?! Cool as f*ck. I was transported back to my youth with those songs. Many many thanks .... very happy. See yer tomorrow'
Did we mention Gloria, New Year's Day and Bad?
If you were at the show, tell us what it was like and post your photos here.
