When we got married I asked for 'The Lord's My Shepherd, I'll not want' (Crimond)
However, at the ceremony he put up 'Oh God Our Help in Ages Past' instead.
I particularly liked the 'Defend us from the stormy blast' bit and we giggled away along with half the congregation.
If I had only known he was bl**dy clairvoyant!
I think
'Signed, sealed delivered' as you leave the building and perhaps go in to
'I put a spell on you'!
