Reply to Possibly Huse Problem

Hey all! I need some fast help.

I recently got a residency at a college evening club. (whee! Seriously though, it's great.) There is a private event toevening for a local bank branch's awards evening . It's a 20-50 year old spread and I'm club DJ. I found this out on fairly short notice that it'll be an 'older' crowd thank what I tune my style for. I have ProgHouse, ElectroHouse, some Top 40, TechHouse and things like that. What the hell should I do toevening ?! I am totally panicking as I am not this kind of DJ, but I still want this to be a fun event for the crowd. HALP.
