Low Sunday

The Tridentine Latin Mass in Adelaide alternates on a Sunday between Missa Cantatas and Low Masses. The reason for this is purely dimplomatic. However following the joys and elaboratness of the Triduum last weekend this Sunday was a Low Mass. However it is still within the Octave and in my opinion a great 1st Class feast.

I wonder, does anyone else in the world have the same logic??
