Weird linkage stemming from the shuffle tonight. "Blue Diamond Mine" by the Texas Rubies sounds insanely like "Where Did You Sleep Last Night?" by Nirvana. Including all the lyrical structure. This isn't too crazy considering the former's genre and the known folk origin of the later, but it is odd when from nowhere a song you've never heard before strikes you as this uncannily familiar. I leave finding an MP3 of "Blue Diamond Mine" as an exercise for the consumer. It appears on Down to the Promised Land.
