Barrett's Privateers is sung in a ship's galley (freighter or something) at an extremely tense moment (Fraser and his partner are undercover and their shipmates are suspicious) when Fraser says "gentlemen, I'd like to get something off my chest" (pause) and then he breaks into "oh the year was ..." The rest of the crew joins in after a verse - it's a great scene.
