how many access points to the spectator terraces were there? form old photos that i've seen, there was a kind of spiral typre staircase which went up and over tower rd (the old apron acces) onto the roof just under where the admin block is at the back of the tower. Also, i think there was a starcase at the back of the old pier A. Was there somewhere from within the concourse that you could get to the terrace from. Also, what and where was the 'TV room?
