Now that was LOUD, love the noise Block 13 brings (remember the Conti Cup last year as an example of where the atmosphere is going to remembered far longer than the actual games) and if people don't like it then they can sit away from that block and maybe jangle their jewellery from the posh seats.
The louder the better, the passion is admirable and sometimes you see the team feed off that noise (when it is loud, soulful, melodic)..
..but please be in tune.
In a small arena, it doesn't matter where you sit (my seat in block 6) you are always going to hear someone on a megaphone singing out of tune. Prolonged chanting off key has a totally different effect on people eventually than a group of tuneful, passionate fans (whose effect invites everyone to jump on board)
You can bet the noisy block chorus leaders in the big European and North American clubs are in reasonable voice.
Liverpool chanting fans are the Pride of the Premier League when they sing 'You'll Never Walk Alone', Wales' Rugby fans when they sing our anthem and other team related songs.
Ditch the embarrassing megaphone and bring on the horns and big drums!
