My Aunt, Lou Buckingham, lives in a gothic mansion in South Carolina with her husband, Buck Dollars. Behind the house is a building that is rumored to be the original town post office. Buck has sort of made it his workshop, I believe. At least, the last time I went there, he showed me around, and there were walls torn out and he was building, building, building, demolishing, adding, because he's this creative mechanical genius who always is doing something. In the added on parts were things like pump organs and this two ton antique piece of equipment that... did... something? Whatever it did, it was impressive.
When people try to be "steampunk," I think they are really just trying to be what Aunt Lou and Buck Dollars are naturally.
I think that's what the song is about, his doings in the post office out back. Oh, did I mention? Buck Dollars and Lou Buckingham are in this great gothic rock band, Wasted Wine. So that's why the song is about them. Do I have the greatest family, or what?
