A giant step from tv special

I took a giant step!
I`m mighty proud of me.
Today, I am the man
I had to be.
Those apron strings at last are cut.
It`s like I grew some wings
And flew out of my Oedipal rut.
I leaped a giant leap!
I made the winning play.
It ain`t July, but hey,
It`s Independence Day!
No more `Sonny Boy`,
It`s `Mister Albert P.`
I took a giant step,
A self reliant step,
A brave defiant step and I`m free!
I climbed a giant peak,
A daring thing to do.
I`m way up high, oh Rosie,
What a view!
I see the future and it`s bright.
It`s no more `Mama anything you say`
From morning till night.
I took a giant step!
A wimpy kid no more,
You never saw a turnaround like this before.
It`s just one small step for mankind.
But for me,
It was a forceful step, a most resourceful step,
A bold and brassy step,
A sassy, classy step,
A self reliant step,
A brave defiant step.
I took a giant step
And I`m free.
