Yes, the red line you have marked is where the steps were, although, they were in a straight line, all the way up to the (then) back of the Lyceum.... marked in your map as Grand Circus. The number of times I have raced up those steps, after getting off my bus in Pond Street, in order to get to the Gaumont, Cinema House,Hippodrome,Palace,etc, in time for the start of the picture.
