Community helpers - song

Community helpers,
Community helpers,
Community helpers,
All around,
They are people we rely on,
To help make a great town.

There are doctors,
And nurses,
Firefighters and police,
Emergencies are why we need them,
Any day of the week. 

There are farmers,
Chefs, and bakers,
Waiter and waitresses,
Feeding people is their job,
They give us food that's good to eat.

There are electricians,
Capenters and plumbers,
On worksites.

They make houses and our buildings,
Safe and sound and build right.

Questions: 

Do you know of any more people, Who are in your neighbourhood, Who work together to build a community, That we live in happily?
