Surprised this hasn't been mentioned. "Food Glorious Food" from the movie Oliver! A re-vamped version was in Ice Age 2.
Here's the original lyrics:
Is it worth the waiting for,
If we live 'til eighty-four
All we ever get is gruel,
Every day we say our prayers
Will they change the bill of fare?
Still we get the same old gruel
There's not a crust not a crumb
Can we find can we beg can we borrow or cadge,
But there's nothing to stop us from getting a thrill,
When we all close our eyes and imagine,
Food glorious food
Hot sausage and mustard
While we're in the mood, cold jelly and custard
Peas, pudding and saveloys
What next is the question?
Rich gentlemen have it boys
IN-DI-GESTION
Food glorious food
What is there more handsome
Gulped, swallowed or chewed
Still worth a king's ransom
What is it we dream about?
What brings on a sigh?
Piled peaches and cream about six feet high
Food glorious food
We're anxious to try it
Three banquets a day
Our favourite diet
Just picture a great big steak fried, roasted or stewed
Oh food marvelous, food wonderful, food magical, food fabulous, food beautiful,
FOOD GLORIOUS FOOD
