So basically, my manager at the pub i work at has decided to start an open mic acoustic night, and since I play I've been given the duty of starting it up. I just want to know what kind of equipment i'm going to need (mics/pa etc). Other people will be playing, so preferably a way to set up more than one guitar/mic at a time

Also, im rubbish of thinking of songs to play, so any recommendations - preferably songs with a female singer, as my friend will be singing as i play. Nothing stupidly common like wonderwall etc, but something that people may recognise. I'm of intermediate ability, so please keep that in mind.

couple song ideas already-
Only exception - Paramore
Crazy little thing called love - Queen
hey oh (snow) - RHCP
