HotI - the Lord's prayer has changed. Not sure how that has happened, but there you go.

Its now something like Our Father, who art in heaven, hallowed be thy name etc . . . Give us this day our daily bread and forgive us our debts as we have forgiven our debtors. Deliver us from the evil one . . . Amen, Praise the Lord.
I wonder if it depends on the school/parish? I know the 'newer' parishes are a bit more forward thinking etc all bar one parish i've been been to still use the 'proper/traditional' one with the only difference being that some now sing it rather than just recite it.
