The Byrds: Pretty Polly
[purchase]
For whatever reason, following the first two most obvious songs for this theme (all together now... yep, those are the ones), this was the first one to come to my mind. This is a dark song by The Byrds. Willie leads poor Polly to a freshly dug hole in the ground and reveals to her that he spent the previous night digging it with a spade. Then he stabs her in the heart causing her to fall into the cold pit.
Now a debt to the devil, that Willy must pay
A debt to the devil, that willy must pay
For killing pretty polly and running away
An evil song for an evil week here at SMM.
