Think there is great potential for having a joined up Upper / Lower section (4) singing section up top (eventually). Good demographic up there now Lower is sold out, and there is the roof there too.
Ironically too, in that setup, we are actually assembled in pretty much an identical position to the old North Stand.
Trouble with Lower behind goal + Section 2, is these seats have been taken up by people that have moved in over the last 10 years, not necessarily singers. The club cannot just turf them out as they have rightfully earn't they seats in good positions due to supporting the club through thick and thin.
So I reckon singers going upstairs is the way forward.
