Here's Ron Angel's song in its entirety...

IRON HORSE OF STOCKTON
(Ron Angel)

Ch:        Come and see the wonderful Locomotion Number One,
The most amazing object that ever the sun shone on.
She's faster than a racehorse, stronger than a dray.
She only feeds on lumps of coal and eats a ton a day!
                
1        Well some had come to marvel and some had come to mock
        But every mother's son that day received an awful shock.
        The steam horse stood there panting, all painted bright and new
        And then she gave a mighty snort and terrified the crew.
        Well first the crowd were petrified and then they ran a mile
        But George was laughing like a drain and his brother had to smile
        To see the shawls and ribbons fly and top hats in the mud
        But then like sheep they all came back to see whatever they could.
        
2        The iron horse stood on the rails as comical as a joke
        And just like any dragon, a- breathing fire and smoke.
        Well first she hissed and then she spat and then she gave a roar
        And then she heaved and out of her the smoke began to pour.
        As off they went a cheer went up and the band began to play
        As four and thirty wagons flew along the wagon way.
        So fast they went some did lament "There'll be a tragedy,"
        But Geordie says "Now don't be daft, we'll all be back for tea!"
                        
3        Well sure enough at teatime the train it did appear
        And there behind the engine, a successful engineer.
        "We beat the Stockton stagecoach, it never had a chance!"
        He shouted to the townsfolk and they all began to dance.
        The seven big guns upon the wharf they fired a grand salute
        The band from Yarm a rousing march they then did contribute.
        Up Stockton High Street they did go and marching two by two
        To celebrate till very late with pints of local brew.

Ron wrote this song to commemorate the 150th anniversary in 1975 of the line's opening. It was performed at the celebrations organised to mark this event.
