1990 Live = non traditional version, personal patchwork, trying to "make the meaning come out clear" as quickly as possible.  Recordings are provided  so as to prove that "experimentation" was done... conclusion:  traditional Iakovos = the BEST...

2006 version:  traditional version and tempo, approximate version of  what was chanted in the Patriarcheion. Notice that, even though the canonarchisma is "faltso" because of vocal instability, the words are "cut up" according to meaning and according to melody, and not just according to "comas" and other punctuation marks  found in present day books...
