I tried Lord Exmouth, but the only song at the Bodleian is about the Crimean War.

Like McGrath, I would expect songs about the Barbary pirates (Corsairs). I tried American Memory as well but found only tons of government papers about them but no pertinent songs.

Odd, Keith, most postings here have nothing to do with the search for Corsair (Barbary) songs. They apparently missed your reference to Cornwall.

I will search for Decatur later. It may lead to one.
