anyone know this? Sung in Sawtell Primary School, New South Wales, in the late 1950s.

First verse:
There's no point in hurting things
something something something wings
Sticking pins in butterflies --
Nothing's happy when it dies.

Chorus:

Everything's meant to be happy
Everything's meant to be gay
Dum de dum dum de dum dum dum
All the livelong day.
