Cosher Bailey had an engine,
It was always needing mending,
And according to her power
She could do four miles an hour
Did you ever see, did you ever see,
Did you ever see such a funny thing before?
On the night run up from Gower
She went twenty miles an hour,
As she whistled through the station,
Man she frightened half the nation.
Cosher bought her second hand
And he painted her up so grand
When her driver went to oil her
Man she nearly burst her boiler.
Now Cosher Bailey he did die,
And they put him in a coffin,
But one night they heard some knocking
Cosher Bailey only joking.
