From a Mini-Wave (or Facing Dancers).
- Arm Turn 1/4;
- U-Turn Back.
Ends in an opposite-handed Mini-Wave.
Shazam is a 2-part call.
Notes:
- 
The U-Turn Back is toward your partner (i.e., Roll twice).
- 
Shazam can also be done from facing dancers:
    Touch; Arm Turn 1/4; U-Turn Back.  This usage is rarely encountered nowadays.
- 
Shazam is defined with an Arm Turn 1/4, not a Hinge.  
    It is inappropriate to call Shazam from a Couple.
- 
Shazam is an 'Any Hand' call.  It can start with either the R-H
    or the L-H.  Many years ago, several callers considered Shazam to be a
    R-H call (hence, from a L-H Wave, only the Centers would be active!).
