Kentish Ballad

When I was a boy, I can remember hearing a song sung in Kent, in praise of that country, which I never could find in print, and of which I am now glad to recollect the following stanza:— "When Harold was invaded, And falling lost his crown, And Norman William waded Through gore to pull him down; When countries round With fear profound, To help their sad condition, And lands to save, Base homage gave, Bold Kent made no submission." Can any reader furnish the remainder, and state who is the author?
