"She was raised in Dorchester. Her family attended St. Francis de Sales parish before it merged into St. Katherine Drexel, so she has a long history within the black Catholic community," said DesRoses.

Guests heard a selection of songs from the choir at the dinner, culminating when soloist Georgia Grace led them in singing "Completely Yes" by Sandra Crouch.

Pierre F. Monette Jr. delivered the celebration's keynote address.

In his talk he emphasized the nature of the Church in current times, accepting people along with their traditions as they come into communion even through difficulty.

"Catholic with a small c means universal, meaning everyone is welcome, and with that I would suggest it means that everyone is able to bring his or her culture to the celebration," he told the crowd.

On the advice of fellow choir member Amon Robinson, Monette had invited Petty to lead a workshop for the choir before the event.

"He kicked off the weekend, that Friday evening, with the choir workshop at St. Angela Parish in Mattapan," Monette said.

Monette said choirs from all over the Boston area attended the workshop and came from as far as Rhode Island.

"It was really phenomenal. It was an excellent way to kick off the weekend," he said.

Monette said the workshop developed familiarity with Petty's musical arrangements, which the choir used in the Mass.

Choir director Meyer Chambers spoke about the history of the choir and its tradition at the dinner.

"Like a tightly knit family, we have come together. We have rejoiced together, thereby multiplying our joy. We have cried together, thereby reducing our pain," Chambers told the crowd.

Meyer Chamber started the choir by bringing together a few members of the local black Catholic community to celebrate Martin Luther King, Jr. Day in 1992.

The 45-member choir and members from throughout the Archdiocese of Boston have traveled nationally and internationally over their 20-year ministry.

On a trip to Italy the choir once sang for his Holiness Pope John Paul II at a general audience.

Other journeys included a Caribbean cruise, where members sang a Mass at the Cathedral of Old San Juan in San Juan, Puerto Rico, and performed at an outdoor concert at Emancipation Gardens, in St. Thomas, U.S. Virgin Islands. The choir also went on a performance tour of Ireland in 2008.

"It was just an unbelievable experience, and the people that we met in all of these different cultures, and it just transformed us. Really, it is what has kept us together," Chambers told The Pilot.

At the dinner Chambers compared the choir's efforts to continue improving to making a cake while keeping "the mixture of our song just a little fresher, just a little newer, while remaining faithful to the flavor for which we have become known," Chambers said.

"Though people love it when we sing concerts, we are at our best when singing the liturgy," he said.
