What about soldiers?

'Hurrah for the Scarlet & the Blue' for one example.

Nic Jones recorded a song which he presumably had from a broadside (Examples can be seen in the Bodleian collection).

In this he refers to soldiers by

'I know that you're fond of Lobsters, both raw & boiled as well'

(He called it 'Sally don't you weep for me' but the song title in the broadsides is 'Unfortunate Sally'.)
