If you want blood, abduction, revenge, gore, etc. nothing beats the Child Ballads. The Bible (Old Testament) is good, too. The material is certainly rich enough to run a few songs off quickly. Oh, yeah, the tale of Salome and John the Baptist, as reworked by Wilde. As my friend, Rick Nestler puts it in his intro, his songs are about singing, death, history, death, love, death [You get the idea.].
