It is that time of the year again where I have my little advent riddle thingy. This year I am going two, one that is lyrics and one that is riddles. For the lyrics I want the name of the song and the name of the artist, and yes this one has several covers, give me anyone of them

1 dec lyrics
Hey little sister what have you done?
Hey little sister who's the only one?
Hey little sister who's your superman?
Hey little sister who's the one you want?
Hey little sister shot gun!

Whilst I was engaged in sitting
I spied the dead carrying the living
What did I see?
