Mr. Moonbeam! - Tom Clancy
Borrowed this from the library the other day and was delighted to see Tom Clancy from the singing irish band the Clancy brothers. I see he's credited as music consultant, very true, he even sings some of the Clancy Brothers old sea chanteys.
This is one of them, Haul Away joe. check it out!

Most of the other chanteys sung in this movie come from an album they cut a few years earlier called Sing of the Sea.
