Two other 5-couple set dances are
 
Brief Encounter by Marj Hendy (1996) (any AABB reel)
5 couple longway set -- PROPER
A1  On the right diagonal (if someome is there), pull by right.  Face 
straight across and pull by left. Same again (like Beneficial  Traditions).  This 
leaves four ladies at the top, four men at the bottom,  and a couple in the 
middle who are NOT each other's partners.
A2 -- on the ENDS star right and then left -- MEANWHILE the couple in the  
middle has a "brief encounter" -- gypsy and swing?.
B1 -- Original first woman (now in 2nd place on the men's side) and  
original fifth man (now in 4th place on the women's side) "unwind" their
star,  
casting up and around the short end (for the women) and casting down and 
around  the short end (for the men), and leading their same sex star buddies back 
into  line -- the "brief encounter" couple split and tag on to their 
respective  unwinding stars.  Everyone's original partner should magically appear 
as  the lines re-coalesce.
B2 -- The original TOP couple (now at the bottom) leads up the center to  
the top, and casts back down (peel the banana) to invert the set.  
And the dance begins again with A1 -- pull by on the right diagonal.   
There is NO recovery time.  
 
Winter Solstice Wendy Crouch 1988
Square set of four couples, with a 5th couple in the middle facing couple  
1.  There's a traditional tune, but any square AABB will do.

Contra dancers sometimes have trouble grasping the hey for 3 instead of hey 
 for 4 -- remembering to tell them that their partner is NOT in the hey 
with them  seems to help. Also, you can change the meanwhile "set and turn  
single" on the sides to a partner swing. Last December I called this one to  
Jingle Bells at the Baltimore contra. The part that the more  analytically 
minded dancers really like is the last bit -- a grand square  with a FIFTH 
couple in the mix.  And the progression is lovely and  smooth.
