Lyrics:

Can't we be happy?
Can't we be happy like the swimming turtles?
Can't we be happy like the bumble bees on the River Tees?
When they buzz they buzz in harmonies.
Can't we be happy like them?
I wanna know.
I am happy when you are happy,
and you are happy when I am happy,
so let's be happy.

Can't we be happy?
Can't we be happy like the tiny mice?
Can't we be happy like the oddball birds of South America?
The oddball birds of South America are happy.
Can't we be happy like them?
I wanna know.
I am happy when you are happy,
and you are happy when I am happy,
so let's be happy.
