Here be Ghosts

The nicest ghosts I've ever seen Were floating round at Halloween, Giving everyone a fright, While witches brewed their spells at night.   Then when I went to Rochester Zoo I saw some ghosties down there too. And I saw Batman, dressed in blue. Are you sure I didn't see you?
Billy Bones is long since gone But still he sings that drinking song Of "Fifteen men on a dead man's chest" I think that you all know the rest.   They tried to take his treasure map, One day while he was in a nap. They took revenge, and d'you know what? They killed him with a big black spot.   They found the treasure, Squire and Jim, Smollett and Livesey were with him. They mostly shared the treasure chest But Long John Silver took the rest.	My name is Billy Bones where my chest has come to rest that's where I like haunting best
