Comments: While talking with journalist Dorian Lynskey, Bono goes into St. Peter's Chapel (also known as Chapelle de Saint Pierre des Pecheurs) and sings "Amazing Grace" with a group of American tourists. The scene is described in Lynskey's article this way:

A warm afternoon in the Côte d'Azur village of Villefranche-sur-Mer. Yachts bob lazily in the bay, diners dawdle al fresco, and Bono, nursing a hangover behind mirrored Ray-Bans, is playing tour guide. He wants to show me the Chapelle de Saint Pierre des Pecheurs, a tiny 12th-century chapel with 1950s murals by Jean Cocteau.

Inside the chapel, he encounters a group of grey-haired American choristers. He spontaneously invites them to sing Amazing Grace with him, to their initial bemusement. Afterwards, one man asks, "Are you a well-known musician? Should we know who you are?"

Lynskey confirmed for us that this occurred on October 1, 2014.
