I was delighted to come across your mention of my book Kol Dodi: Jewish Music for Weddings, which contains the music scores for the vocal music on the corresponding 2-CD set. In response to the many queries I received about where to get the scores for the instrumental music on the CDs (which do not appear in the original book), I subsequently published a companion volume:
Jewish Wedding Music: Processionals and Recessionals: Kol Dodi Vol. II: Instrumental Music for the Jewish Wedding Service. As far as I know, there is no similar collection of fully arranged authentic processional and recessional music which can be used in place of the ubiquitous Wagner, Pachelbel and other “non-Jewish” melodies.
