Love that one, Charley!
When I saw this thread I thought it may be about 'The Fireman's no for me', but that is a different kind of fireman (one who works on a steam train)

Oh the sailor comes home when his voyagings done,
And the soldier gets tired of following the drum,
And the collier will sit by his ain fireside,
But the fireman's one love is the engine he rides.
