As there are relatively few competitors in this afternoon's age groups, they are dancing each section sequentially, with age groups doing their hard shoe, then changing when all age groups have danced and all age groups then doing their soft shoe. At least that is what I think I heard :)
They are dancing on the stage, two at a time. For those who have been to Dickson College, it is a large stage in both width and depth and has a very good sound. The adjudicator, who is perched on a somewhat small elevated set of block, has an excellent view and can hear every beat and shuffle.
