The official list of musical selections has not been released, but an ABC News report provides some inkling of the kind of music and liturgy the the Archdiocesan committee has selected for the Washington Nationals public mass:
When Pope Benedict XVI celebrates Mass at Nationals Park on April 17, he will be accompanied by four choirs totaling 570 members, singing in ten languages from across the Archdiocese of Washington.
He will hear a 65-voice Intercultural Choir with members from 35 countries singing in French, Zulu and Spanish, among others. A 250-voice Papal Mass Choir and a 175-voice Children's Choir will sing in Latin. The uplifting sound of an 80-voice Gospel Choir will ring out across the stadium. . . .
Musical highlights during the processions and prelude the program includes:
- All choirs performing the opening Spiritual "Plenty Good Room," newly arranged by Washington Symphonic Brass founder, Phil Snedecor
- The Children's Choir singing "Send Forth Your Spirit" by Andrew Wright and "Ave Verum" by Mozart
- The Gospel Choir singing "I Call upon You God" by Leon Roberts and "Lord Make Me an Instrument" by Roger Holland
- The Papal Mass Choir singing "Sing Aloud Unto God Our Strength" by Daniel Nelson and "Spirit of God Within Me" by Robert LeBlanc.
