This was actually my Mum's! For years,she would go around the house singing the harvest Hymn "Bringing In The Sheathes" ...but she sang "Bringing In The Sheep" !
Another hymn one ( my boyfriends) When he heard the lyrics "We Are Weak But He Is Strong" he thought it was "we are weak,but tea is strong" !
