into a quandary. He had begun and nearly completed a score for a St Matthew Passion, a project which he began in 1725 but put aside for a revival of his St John Passion, when he again for some unknown reason set aside the project (he would complete it and first perform his St Matthew Passion on 11 April 1727). Instead he decided to revive his Weimar pastiche. This work was performed on 19 April 1726. For this work, he changed two movements (Nos. 14 and 29 of the Weimar work) and, to fit it to the Church Ordinance for Good Friday Vespers services in Leipzig, he split it into two parts by adding a chorale. The violin I part for this work (BWV deest, BC D 5b) is missing in all his new additions (and has been reconstructed), but on the whole, the parts are more complete. This work has come down to us in the form of a vocal score and parts set dating from before 1726 in the hands of Johann Sebastian Bach, Christian Gottlob Meißner, and Johann Heinrich Bach, and is currently stored in the Staatsbibliothek zu Berlin under the Catalogue number D B Mus. ms. 11471/2. The title page (like the Weimar one) reads "Passion Christi / secundum Marcum [korrigiert aus Matthäum] / à 5 Strom 4 Voci / di Sigre / R. Kaiser." In this version the following parts are by Bach: No. 9b: "So gehst du nun, mein Jesu", BWV 500a, BDW . No. 14: "O hilf Christe, Gottes Sohn", BWV 1084, BDW , which is a variant of the setting included in the Weimar version. No. 29: "O Traurigkeit, o Herzeleid", BDW , which is a variant of the setting used in the Weimar version The sequence of movements in this version is as follows: Prima Parte Sonata and Chorus: Jesus Christus ist um unser Missetat willen verwundet Recitative (Evangelist, Jesus, Petrus): Und da sie den Lobgesang gesprochen hatten Aria (soprano, basso continuo): Will dich die Angst betreten Recitative (Evangelist, Jesus): Und nahm zu sich Petrus und Jakobus und Johannes Chorale: Was mein Gott will, das g'scheh allzeit Recitative (Evangelist, Jesus): Und kam und fand sie schlafend Recitative (Evangelist, Judas): Und alsbald, da er noch redet Aria (tenor, violins, continuo): Wenn nun der Leib wird sterben müssen Recitative (Evangelist, Jesus): Die aber legten ihre Hände an ihn Recitative (Evangelist): Und die Jünger
