I remember one woman who came in to audition could not stop praising us in the first rehearsal for how talented we were.
Second rehearsal same thing.
Just before the third rehearsal she posted one of those cryptic status' on Facebook, something like "I won't be going down with this sinking ship". 15 mins before rehearsal she cancelled and we never saw her again.
We were a local band playing for beer money, nothing more, but she acted like we were huge or at least going to be.
Don't even get me started on the bloke who turned up with his own mic, an X-Factor karaoke mic! He said he needed two hours before every rehearsal to warm up his voice...
