Seeing as this match thread has been thrown over to seating ideas, here is what I would do.
Darwen End lower turned into an unreserved singing section. It is such the most obvious answer to everyone's needs I really cannot see why no fan has suggested it properly previously.
Less fans are inconvenienced by such a move, fans have the choice to move to the aforementioned singing section rather than have it thrust upon them, plus it is unreserved and if it proves popular it also gives home fans a chance to outsing away fans for once.
Plus who knows, we might sell enough tickets so that the club doesn't have to allocate entire stands to away fans.
I'll repeat, it is only my thought, I've never discussed it with any colleagues because its not really my position to do so.
And for those fans who would complain about moving to the Darwen End, ask someone 30 years older which stands the hardcore Rovers fans were in.
