There is a tantalising suggestion from meself in this Jim Lad thread that "Cape St. Mary's" is derived from a cowboy song. Can anyone comment further? I can imagine a lyric something like:

Take me back to my western hills
Let me ride the open prairie
Where the coyotes wail and the goshawks sail
With my friends the Sioux and Pawnee
Let me ride the open prairie

or whatever . . .
