that's a very interesting perspective, Elixir- I like it!
last fall/winter I was extremely preoccupied with this song & started researching the concept of "bone houses". here are some of the best examples I've found, http://www.panoramio.../photo/45259040
, from the Istre Cemetery in Morse, LA. See also, http://www.katc.com/...e-house-legends
. although there is some speculation as to why these 'houses' came about and, also, why the practice of building them died out, it appears families usually got to work building the house right around the time of their relatives death, as a shelter for the 'bones' (shelter from 'dead weather'?)
personally I've always thought of 'Bone House' as a twisted view of marriage/relationships, or kind of along the lines of "you've got her in your pocket"
