Wolfgang Sawallisch would have been conducting the Munich Philharmonic Orchestra
Heinrich Hollreiser could have been conducting the Bavarian State Opera or Bamberg Symphony Orchestra
Three conductors are listed on the first 6 tracks. I know that Heinrich Hollreiser was conducting the Munich Philharmonic Orchestra so I have added the orchestra into tracks 7-10, but could we have a correction for the other tracks, showing which orchestra was conducted by which conductor. Presumably one was directing the Chorus while the other was conducting the orchestra.
