Answer:
Beautiful girls strut and sexy men 'do their little turn' on this.
Always old, sometimes new. Never sad, sometimes blue. Never empty, sometimes full. Never pushes, always pulls.
A little house full of meat, no door to go in and eat.
I am the hole in the night, the ever watchful eye. I return in a cycle, to enlighten the sky.
I tremble at each breath of air, and yet can heaviest burdens bear.
All about, but cannot be seen, Can be captured, cannot be held, No throat, but can be heard. Who am I?
