There is also a WW1 version often known as "The Khaki & the Blue" in which the wording differs slightly. Probably in the active recruiting of the time various local references were included to encourage men from that particular area to enlist. A good example of this is the Version recorded by the Watersons:

Its called simply "The Ploughboy" here, but it was announced at live gigs by the Watersons as being "the 'Tatton-Sykes Waggoners' Militia Recruiting Song"

(Tatton-Sykes was a member of the 'landed gentry' in East Yorkshire, who raised a Company for one of the War-Service Battalions of the local Regiment (The East Yorkshires) from the workers on his estate, & men of the surrounding Villages)
