Boudouris explicitly writes that a slow tempo is to be used for this particular version he wrote down. He also specifies that the chronos to be used is double (diplous) as opposed to other pieces which he indicates they should be chanted in chronos simple (haplous).

Notice the subtle but noticable interpretation of some petastai signs in the text. Also notice that he doesn't follow exactly the analyseis recorded in Boudouris' score. Finally notice that the co-chanter (Pringos) does small variations of analyseis here and there without that destroying the coherence of the chant. The piece can be chanted at various tempos (fast, slow) depending on the occasion/time in the service.

Michail Lagoudakis offered this recording from a recent concert at Duke University (US). The 7 chanters performing come from various backgrounds (different schools, including Karas) and the hymn was performed on the spot (without music) with audience participation (clearly heard). This recording perhaps represents a "popular version" of the hymn.

Notice the overdone elxeis and the repetitiveness of interpretation. The mechanical interpretation of analyseis which, however, are in concept the closest to what Boudouris wrote down (see score above). Finally notice the identical performance style with that of Angelopoulos' teacher choir, that of Simon Karas above. Compare the subtle interpretation of petastai by Nafpliotis above with the over-simplified, rigid interpretation here.
