I did wonder about the names....
OK - Spiral Staircase: starts like a First Move (I think we have that in common), so you bring the lady in to your side. Then, as you turn her out, you signal it's a "Spiral Staircase" by simultaneously pushing her out, so that there's some space between you. Then, the lady is turned anticlockwise on the spot, as the man moves across her, and back into that locked position at the start of the First Move. (if you get my drift so far)! Then, you can optionally travel around for 3 beats - then you repeat from the push/turn out, turn, and exit like a normal First Move.
Zany could be a double. It's as a normal Pretzel, except on beat 3 (assuming 1 is the step back) you drop the lady's right hand, and on beat 4 you spin her clockwise in front of you, holding her left hand - then repeat, but as if it were mirrored (you would signal right hand behind your back).
Clear as mud, right?
