Diane Taraz (from Massachusetts) has written a fine song about "The Sea Serpent of Cape Ann." (Cape Ann is North of Boston.) This giant creature has been reported over the centuries by many observers, dating back to 1638. The song appears on Diane's CD "Beat of the Heart" (2003); it's also on the Gloucester Hornpipe & Clog Society's "Liberty" CD ( 2008).   A YouTube version can be heard at http://www.youtube.com/watch?v=capJ9Lrlats .   That would be Sea-Serpent of Cape Ann if the blue clicky thing works.
