Hi folks -- I'm the one who wrote Venezuela to Trinidad in 2005/6, and Barry was the first one who learned it -- we used to sing it together, alternating verses, Wednesday nights at Cameron's in Gloucester. The song depicts life on the Norwegian tanker Margaret Unstad, and several months of short back back-and-forth trips between Venezuela and Trinidad. The ship was owned by the husband of skating star Sonja Henie, and their alcoholic son ("Lars" in the song) shipped around with us all over the world.
They say this chantey is being sung in England and Australia. There are two middle verses I rarely sing, cuz I think it makes the song go on too long. And the words and tune seem to be evolving over time --   OK with me. Anyway, let me know if you'd like me to send you a score or a recording of me singing verse 1, or of other chanties I wrote and sing in Gloucester -- Ahoy! -- Roger
