Great, thanks for the tip.
I need three violins, cello, flute and a double bass player for the lower notes on the cello sound.
Will they bring chairs ? A need a squeaky one for a note.
Not only will they not bring chairs (well, the flutist might agree to bring one -- for extra money), they will complain about the chairs you provide, especially the violinists. You should consider hiring only two of those. Any more than that, and they show tendencies of "herd mentality" following the Alpha Violinist (the one sitting at the front on the outside) and will do anything and agree with anything this person says, no matter how insane. Tell the double bass player to bring beer. They're always more than happy to do that. If you want hard liquor, you need to hire a trombonist or two.
