Bless all the dinner children, in the tender care

The story:

This was my friends mother who got hates singing this song at primary school. Everyday the school canteen staff would line the children up into two queues, being the ones that look their own packed lunch (the sandwich children) and the ones that had hot school meals (the dinner children). My friends Mum was very upset that she had to sing about those children getting blessed when she missed out just because her Mum sent her with sandwiches.
