From an Eight Chain Thru (or Parallel R-H Waves).
Right Pull By; Outsides Courtesy Turn as Centers L-H Star 1/2 to
  face the Outside Couple.
Ends in an Eight Chain Thru.
Notes:
- 
For those coming into the Center, the result of the L-H Star 1/2 is
    as if you had done a Cross Trail Thru (but it is danced similar to a
    Belle Walk, Beau Dodge followed by a Walk & Dodge).
 - 
By definition, the Roll direction for all dancers is toward
    the Left.  This was done so that a Cross Chain Thru & Roll
    is identical to Cross Chain & Roll.  For example, Cross
    Chain Thru, Boys Roll means Boys Cross Chain & Roll as
    Girls Cross Chain Thru.
 
 Variations: Star 3/4, Star one full turn.
