Really?? The genuine article or a local licensed knockoff?
My last footie game in London was at Highbury, and my lasting memory was of a world war taking place in the stands with an incidental game on the pitch.
To all appearances it is the honest Singha brew (I had previously had it in bottles in the States) - Singha is the club's official beer sponsor.
I've been to several matches at The Bridge and, apart from some mild scuffles in the away end, haven't had any trouble. High ticket prices, banning orders and CCTV identification (among other things) have pretty much put paid to the old hoolie culture (although I understand it's still more or less alive in the lower leagues).
