See, I have a problem with this. So many times camera crews have come over to us (home and away), and said- do a chant for the camera!
No, you don't force it. If they want to experience the supporters atmosphere, set up in front of 113/112, or get them in the section. I hate the manufactured "support" they think they can get from us. Just like those "300 style" BMO ads. All it really does is make a mockery of us.
