I think that it conveys something of the joyful exuberance that prevails in traditionalist circles.
The words to the verse are:
Gloria tibi, Domine,(If anyone from CIEL can let me have the text of the rest of the hymn by email to save me typing it out, I'll be glad to post it here.)
Qui natus es de virgine,
Cum Patre et Sancto Spiritu
In sempiterna saecula.
Ave! Ave! ora pro nobis
Sancta Dei Genetrix.
O Lord, Who were born of the Virgin, Glory to You with the Father and the Holy Spirit for ever and ever. Hail! Hail! pray for us O Holy Mother of God.
