Our stadium must have weird acoustics, from the back of the East Stand only heard the Charlton fans a couple of times. Wasn't impressed by them at all.
Also, these days their fans aren't from just south of the Thames. 90% of them are bussed in from crappy sattelite towns in Kent. Everyone I've met from deep south is Wall through and through, they actually, weirdly, have plenty of fans who were brought up in Charlton. They're a proper nothing club who had a little run in the Premier League. Palace and Millwall view them as the embarassment they are, most "wannabe" football club going.
