Battlefield 1942 Easter Egg - Instruments!

Well,first you have to be up to the level when you have to cut comunications in that sort of snowy town and in one of the buildings walk through and up some stairs and come into a nice cozy room.In it,youll find a piano and a base violiny thingy propped up next to it. go to the piano,jump up in front of it and press USE, (default E) and youll play a nice little tune.Same with the base violin. just walk up to it,crouch and press E!
