For once there is some background info on Op 67 on Wiki;

Johann Baptist Joseph Maximilian Reger (19 March 1873 – 11 May 1916), commonly known as Max Reger, was a German composer, pianist, organist, conductor, and academic teacher. He worked as a concert pianist, as a musical director at the Leipzig University Church, as a professor at the Royal Conservatory in Leipzig, and as a music director at the court of Duke Georg II of Saxe-Meiningen.

Opus 67 was published in 1903 the year before this organ was opened so maybe some enterprising recitalists included a few of these pieces in their programs on the new organ.
