Reminds me of the song Sheela-Na-Gig by PJ Harvey. Growing up I had no idea what it was about, only later to find out (as with so many other things in life).

Due to your link I'm now listening to the Dry album from start to finish and really enjoying it.
So thanks friend for brightening my Sunday morning!
