The running commentary at the West Mids Show was excellent and helped people to understand what was going on.
At Blackpool you do need people to draw the crowds in and make them feel part of the event.
Put or give a sticker to any spectators with a Team name on it and ask them to cheer/support that team, when they are playing and get some crowd participation.
They will feel obligated to stay around at least to see their team play and any noice created by crowds, draws in more people.
Ask teams to respond to their new found supporters , waive at them, show a bicep, pout etc etc they have all been doing in the mirror for years, so that should come easy
