The choir has a special interest in locally composed pieces and commissioned works.  BCCS has commissioned pieces to mark many special occasions in its history, including Richard Averre's Magnificat for the 10th anniversary, Richard Wargo's Voices in the Mist for the 15th anniversary, Gregg Smith's Gloria for the 20th year, and Steven Sametz's Nunc Dimittis, He Brings Us Joy for the 25th anniversary.  In 1997, the choir commissioned Will Ayton to compose a setting of Psalm 95 entitled O Come, Let Us Sing to mark Elma Heckler's 20th year as Artistic Director, and the choir premiered Alice Parker's Shepherds and Angels in December 1999 in honor of Elma's retirement.  To celebrate the group's 30th anniversary season, BCCS commissioned its largest-scale work: Rachel and her Children - Small Hands, Relinquish All by Philadelphia composer Robert Maggio.  The work for BCCS, mezzo-soprano soloist, youth choir and a wind and brass ensemble was funded by a major first-time grant from the Philadelphia Music Project of the Pew Charitable Trusts.  It was premiered in Doylestown, Langhorne and Philadelphia, under the direction of Thomas Lloyd.
