Lyrics:

Your heart is your own little inside joke so guard it
The moon is just a little bed light above your head yeah

So you can go to sleep and some sheep
Where the grass is green
Don't you worry about it all
When they try to get you down just think of me
It's in the ABC
of growing up

The world is one big jungle gym for you to climb in
Your eyes are big colourful marbles
don't you lose them now

So you can go to sleep and some sheep
where the grass is green
Don't you worry about it all
When they try to get you down just think of me
It's in the ABC... of growing up
Ohoh
Of growing up, yeah
So..
