The Coasters - Poison Ivy (Okay this song's actually about getting an STD but Poison Ivy is quite a good Halloween outfit, right?)
The Cramps - I was a teenage werewolf
Can't really omit this one!
Cliff Richard's pretty scary, right?!
David Bowie- Scary Monsters & Super Creeps
Black Sabbath - Wizard (Basically any Black Sabbath works well! My dad will appreciate me putting this on the list...)
Fantomas- Spider Baby ..Tom's song of choice!
and finally some Dead Man's Bones.. ah.
