I was at the game - attendance was poor - only around 16000 so stadium was half full, but interestingly they filled up the stand opposite the tv cameras so on the telly it probably looked quite full.
Game was pretty slow to start, with little atmosphere until Reading scored at the beginning of the second half. This woke the Birmingham players up a bit and the game got quite exciting.
Some fans got arrested ejected too (dunno what they were doing tho) ;)
