Wow I must be going deaf . IF you hear these noises point it out to the stewards and they I am sure will deal with it and shame on you for not reporting these incidents before as I can only assume that you did not report it otherwise I am sure Levy would have been on the rampage.
If I had heard these shouts I would have been reporting them immediately and if I saw the offenders I would have pointed them out.
fans film everything these days it's laughable footage hasn't come out, mate
