A Catholic samba group in Rio de Janeiro changed its parade plans after the nightclub fire that killed more than 230 people, most of them students from the local university in Santa Maria.

The Catholic samba block group known as Revelry for Christ was scheduled to parade through downtown Rio Jan. 27. Instead, the group turned its parade into a religious procession, with approximately 30,000 would-be party-goers singing Catholic hymns and making their way to Rio’s metropolitan cathedral, where Archbishop Orani Tempesta celebrated Mass.
