....AND ROLL`

    ‘...And Roll’ is on the Plus list.  It is an extremely versatile call.  Commonly listed as (Anything) and Roll, the call can be done by any dancer who has turning body flow from the previous call.  The call requires you to turn in place one quarter more as a single dancer in the direction of your body flow.  For example: from a static square, Partner Trade and Roll.  You complete the Partner Trade (ending as a couple facing out) then Roll one quarter more to end up facing your partner.  Remember Roll is a call that is done by individual dancers.  Your Roll is dependent on your own body flow  alone.
Let's look at some individual calls to which we can add a Roll.  The requirement is that the previous call must have a turning direction in the flow.  Star Thru and Roll.  The boys turn 1/4 right then Roll 1/4 right, the girls turn 1/4 left and then individually Roll 1/4 more left.  Note that the roll is done individually and that it is dependent on the individual's body flow.  In this call, the boys and the girls roll in opposite directions, ending up facing one another.  California Twirl and Roll is like a Partner trade and Roll.  The dancers will end up facing.  How about a hard one?  Right and Left Thru and Roll.  The final part of the call - the Courtesy Turn - determines the Roll direction.  After the Courtesy Turn the dancers must individually - in place - continue turning 1/4 more to the left.  The reason that this call is hard is that you are working as a couple, then you must INDIVIDUALLY roll 1/4 - ending up as Tandems (one dancer behind the other facing the same direction.)
Swing Thru and Roll.  (from right handed ocean waves) All turn 1/2 by the right (those on the outsides can roll now) then those who can - the centers - turn 1/2 by the left (and then roll to face).  You will end up in Double Pass Thru.  From Left handed waves Swing Thru and Roll is completely different!  Since the right hand is in the center, the centers turn 1/2 by the right, then the center and adjacent end turn 1/2 by the left and everyone Rolls, this time ending up in Eight Chain Thru.
Wheel and Deal and Roll.  From lines of 4 facing out.  Each couple wheels in - the couple on the right wheels in to the left and then each dancer rolls left, the couple on the left wheels in to the right and the each individual dancer rolls right.  The result?  Left handed Ocean Waves.  From two faced lines:  From right facing two faced lines: all wheel in to the right and roll right.  The result is a left handed ocean wave.  From left facing two faced lines the result is right handed ocean waves.  Ferris Wheel and Roll is the same idea.  Your individual roll is determined by the direction in which you wheel in.  The result is now two faced lines.  Ferris Wheel and Roll from left facing two faced lines results in right facing two faced lines and from right facing two faced lines results in left facing two faced lines.  Please note here:  if you style as you dance, you are responsible for correcting your roll direction.  For example, if you twirl under when you are doing a Ferris Wheel you will be turning the wrong direction for a Roll.  It is your responsibility to correct your turning direction if your styling causes you to turn in the incorrect direction.
What about a call like Trade By in which four dancers have turning directions and the other four are Passing Thru?  Those who can - Roll.  If you cannot Roll after your part of a call, don't roll.  Pass to the Center and Roll is like Trade by and Roll.  Both result in four people Rolling and four people unable to Roll.
Touch 1/4 and Roll is equal to Box the Gnat.  The dancers end up facing one another.  Hinge and Roll (mini waves) is the same result - facing Dancers.  Hinge and Roll from ocean waves ends in Eight Chain Thru.  Note that Hinge and Roll is also like Single Wheel from the Advanced List.  Recycle and Roll from Right ocean waves ends in Left ocean waves and vice-versa versa.  Linear Cycle (Hinge, Fold, Double Pass Thru, Peel off to the Right) and Roll (right) ends in a left handed column.
Roll can be added to a series of calls with surprising results.  From a static square: Heads Right and Left Thru, Sides Pass the Ocean results in Quarter Tag (which is an Ocean Wave down the Center with the ends facing in).  Now let's add a Roll and a Spread:  Heads Right and Left Thru and Roll (it's left) and Spread, Sides Pass the Ocean.  The result is now Diamonds.
Remember, the whole key to Roll is staying in the footprints of your ending position from the previous call and turning individually 1/4 more in the direction of your body flow.
