Have Cubs with each letter on posterboard with their part written on back

P  A Pinewood Derby is fun for all,
    But the whole family must answer the call.
I    I will enter the competition real soon
     To win or lose or whatever my doom.
N  Neatly I painted my car with dad's expert help,
     But please let me run it all by myself.
E  Excitement runs all though the night,
     No matter who wins, it will be alright.
W We would all like to come in first,
     But if not, our bubble wouldn't burst.
O  On with the races, don't hesitate,
     For this Pinewood Derby can't wait.
O  Open the gates, down the track; then we can rest.  
     For, being Cub Scouts, we've done our best.
D  Don't mind tonight, where your car places;
     Cub Scouting will help you through all life's races.
