Pelican Pens: Limericks

OK, first attempt.  Still thinking…

There once was a bevy of writers
Planning a week of all-nighters
To write a screen play
With plenty to say.
They’re Pelican Pen screenwriters.

A John and a Mary were named
As leads in a story just framed.
As George leads the band,
With script in his hand
All hoping to win some acclaim.
