Oh, I know what you mean seed - I can't seem to forget those substitute words. As a teen I would organise music for Mass every Sunday. Due to a perpetual feeling of embarrassment (caused by puberty I suppose) which intensified during solemn moments I could not help giggling when during the poignant "Lamb of God" - remember...

Lamb, lamb of God
You take away the sins of the world
Have mercy on us

... our guitarist Kieran would sing instead ...

Lamb, lamb of God
Tastes better with mint sauce...

of course, only I could hear him - how difficult is it to sing and laugh at the same time INTO A MICROPHONE IN FRONT OF THE CONGREGATION. Kieran would also play death metal guitar riffs during our version of Glory Be.
