Singer Monroe performed her song "Regarde !" during a prayer vigil attended by 80,000 young people at the Saint-Denis stadium, located north of Paris. The event took place on Friday, September 25, at the Stade de France, where Monroe took the stage to perform the track as part of the vigil that Pope Leo XIV was scheduled to attend. The song, which focuses on themes of love, blends elements of pop music, operatic singing, and musical theater. Monroe had previously performed "Regarde !" at the Eurovision Song Contest in May of last year, where she finished in eleventh place. The prayer vigil was a significant gathering for young people, offering a mix of pop-inspired worship music, opportunities for dialogue with the pope, and the display of religious relics. One of the highlights was the exhibition of the "holy tunic of Christ," a revered religious artifact preserved in Argenteuil, a town in the Val-d'Oise department. This event aimed to bring together youth in a spiritual and communal setting, combining modern music with traditional religious practices. Earlier in the day, Pope Leo XIV celebrated vespers, a traditional evening prayer service, at the Cathedral of Notre-Dame. This service was attended by clergy, deacons, and seminarians, marking another important moment in the pope's schedule. The day's events reflected a blend of religious tradition and contemporary engagement, aiming to connect with both young and older members of the faithful. Monroe's performance at the vigil highlighted the growing role of contemporary artists in religious and cultural events. Her music, which fuses different genres, resonated with the audience and underscored the event's goal of bridging modern expression with spiritual reflection. The vigil served as a platform for both worship and community, drawing thousands to participate in a shared experience of faith and music.
