Branwen,

I don't see that anybody's actually given you the chords for it, so I'll try to do it from the version I do — hope the HTML stuff works. Here goes:

VERSES:
(C) Have you heard of the ship called the (G7) good Ruben (C) James
(C)Run by hard-fighting men both of (G7) honor and of (C)fame
(C) She flew the Stars and (C7) Stripes of the (F) Land of the (C) free
(C) But tonight she's in her grave at the (G7) bottom of the (C) sea.

REFRAIN:
(C)What were their names, (C7) tell me (F) what were their names
Did (G7) have a friend on the the (C) good Ruben James.
(C)What were their names, tell me (Dm) what were their names
Did (G7) you have a friend on the (C) good Ruben James.

Hope this is helpful...

cheers,

david
