In the published version of John Clare's notebooks is a song (probably from his father - otherwise one of his local singers)called Ocean's Glory, about Grenville and with a similar structure to Benbow:

Come all you seamen bold and draw near, and draw near,
Come all you seamen bold and draw near.
It's of an admiral's fame, bold Greville was his name;
How he stormed along the main, scorning fear till he died,
And brought his navy fame - you shall hear etc.

I once took down a copy of it, but it and I have long since parted.

Does anyone have a copy (or Library access to one)?
