Saturdays in the back room rotate between DJ Fluff and the Jim/Sheena symbiote, the latter pull quite a lot of people into the club, probably because they have lots of friends. It has been commented that Fluff plays a lot of the same stuff that the Lucifer symbiote play in the main room, but y'know, none of us are mind readers (my powers are limited to superhuman agility, optic rays and nigh-invulnerability); so maybe a tighter (or looser) remit in the back room is good idea.
