I agree with this. I come up from the south coast on my own whenever I can but usually alone. I will sing as loud as I can but I can see that some people would feel a bit daft if nobody was singing around them, also siting in an orderly fashion doesn't really help get the party rocking. At concerts and festivals it's a much better atmosphere when everyone is standing up and jumping and waving there arms, and also to have your mates or like minded people next to you.I don't buy this. There aren't THAT many tourists at Anfield. Really, there aren't. In the seat I'm in at the moment the vast majority of people around me are locals and/or regulars, the atmosphere is still flat in that section.
There could be 10,000 tourists in Anfield and you'd still have more than enough fans to create a good atmosphere.
Safe standing and a scheme designed to allow you to stand/sit with all your mates (or other like minded people) at the game is the only way to improve the atmosphere. After every away game I've ever been too I've come away hoarse, very rarely does that happen at Anfield. I'm simply not going to sing on my own for 90 minutes at a 3 o clock game against Sunderland when nobody around me is joining in.
It's always been the same though, I remember going to grounds in the 70s and early 80s with my dad and it was always the terraces that were making the noise. The feeling was always that the stands (seats) were the posh seats or for the families and you weren't going to get any noise from there. All that has changed is that all stadia are now just filled with the posh seats.
I've said it before but the simple answer is to have safe standing at the front of the kop and sell the tickets on the day. Young kids, mates, can all stand and sing together.
