The events, all part of the Cathedral’s “A Call to Compassion,” a weekend of commemorative events, include concerts by military musical groups, a speech by President Obama and performances by Patti Labelle, Alan Jackson and Denyce Graves.

In addition, the Cathedral’s planned interfaith prayer vigil scheduled for 8:30 a.m. Sunday has been moved to Washington Hebrew Congregation at 3935 Macomb St. NW.
