This piece was in a file entitled, "RP scores, work on." It is Proulx's SAB arrangement of Jacques Arcadelt's original. Here Proulx not only shifted the piece to SAB (see the included original SSA arrangement), he also also added an English text. It is unclear if this has ever been published. There is another edited arrangement of this song by Proulx (for SATB choir) in another file (#503).
