STARTING A POEM WITH ZED

I want to write a poem that starts with zed
I have to complete it before I go to bed 
Shall I call it Zulu or perhaps maybe Zoo
Can't decide so I will leave it up to you

I have finally decided I will call it Zoom 
Now I can at last sleep in my bedroom 
Zoom will be about rockets and flashes 
Chasing about and no doubt dashes 

Starting a poem with zed was a real hard choice 
Put it together so I will celebrate and rejoice 
Zed why do you have to be a difficult letter ?
Surely starting a poem with A would be better
