Is this a good poem?

Forgive us now for what we've done

It started out as a bit of fun

Here, take these before we run away

The keys to the gulag

O children

Lift up your voice, lift up your voice

Children

Rejoice, rejoice

The cleaners have done their job on you

They're hip to it, man, they're in the groove

They've hosed you down, you're good as new

And they're lining up to inspect you

O children

Lift up your voice, lift up your voice

Children

Rejoice, rejoice

Hey little train! We're all jumping on

The train that goes to the Kingdom

We're happy, Ma, we're having fun

And the train ain't even left the station

Hey, little train! Wait for me

I once was blind but now I see

Have you left a seat for me

Is that such a stretch of the imagination

Hey little train! Wait for me!

I was held in chains but now I'm free

I'm hanging in there, don't you see

In this process of elimination

Hey little train! We are all jumping on

The train that goes to the Kingdom

We're happy, Ma, we're having fun

And the train ain't even left the station

Hey little train! Don't wait for me

Once I was blind but now I see
