Formation, for a small chorus of 12?

It's a bit hard to face around. It's not like it's a bonfire, is it? The formation of 12 people singing alone can be varied to "cover all sides", but what about the four backup dancers?

Let's start by facing one side, with the boys lined up horizontally and the girls lined up on both sides. After singing a paragraph, the boys went forward, then turned around, facing the opposite side, the two girls on the outside of the original leaning towards the boys, the original inside to the sides of the separation, so that the inverted eight-shaped. After singing another paragraph, the two girls walk into parallel formation, a group to the left, a group to the right, each facing both sides of the audience, the boys are free to choose the direction to continue to sing ......

The four dancers will choose the four corners of the bar, or move at random.

Can you read the above?
