Has anyone been able to sneak in a m4/3 camera into a concert...

Has anyone been able to sneak in a m4/3 camera into a concert where only point and shoot cameras are allowed? I'm so undecided and want to buy either a m4/3 camera to use at concerts, or buy the RX100. If I buy a m4/3 I would have to hide the camera and lens, or maybe it could pass as a point and shoot camera with a pancake lens? Has anyone gotten in with one of these?

I've been able to sneak my sister's E-PL2, but one time they told me to take it back to the car. I had to use my iPhone's camera, and those pictures came out blurry. I would go for the RX100, but a m4/3 camera is cheaper. :/ I don't know what to do!
