If 6 Was 9

If the sun refused to shine
I don't how
I don't mind

If the mountains fell in the sea
Let it be
It aint me

Got my own world to live through
Ain't gonna come near you

If a 6 turned out to be 9
I don't know how
I don't mind

If the hippies cut off their hair
I don't care
I don't care

I've got my own world to live through
Ain't gonna come near you

If the sun refused to shine...

What child is this...?
