Are you thinking of:
We hasten to your patronage O Maiden full of grace. We seek your help in every need our queen and advocate. And keep us free from sinful deeds, O virgin most beloved. We ask you to forsake us not, give mercy from above.
it goes on and says: And cover with your mantle blue, your children who await, salvation and redemption day, our queen and advocate...
It is entitled, We hasten to your patronage and is found in the Blue Marion Hymn book which I believe was put out by the Byzantine Seminary press...unfortunately my copy is at the cantors stand so I don't have the rest...I believe it is also found in the old BCC pew books...
