|Set:||3 couple longways.|
|Acknowledgements:||Includes some of the best figures from Grace Jackson's and Val ???'s dances.|
|Trivia:||Named after the implausible one-way system in Cambridge, principally due to the final figure which is equally implausible.|
|A's are 1,4&5; B's are 2,3&6.|
Odds are 1,3&5; Evens are 2,4&6.

|4||Middles quarter turn right.|

|As A's chorus, but swap roles for A's and B's.|
|Figure 3:||Pairs Hey (Space Invaders)|
|1-16||1&2 face down; 3,4,5&6 face up.|
Dance a hey for 3 with couples dancing as a unit. Each person turns alone and so will be on the same side of the set throughout the figure.
For this to work, the set has to get slightly narrower and the hey stretches it along its length. Partners must mirror each other exactly.
|Evens finish standing.|
|1||Odds step forwards towards partner.|
Evens stand still.
|2||Odds quarter turn right to face down.|
Evens quarter turn left to face down, using a two-footed jump and remain standing.
|3-4||Repeat 1-2, evens turning right to face odds line again.|
|5-6||Repeat 1-2, evens turning right to face up.|
|7-8||Repeat 1-2, evens turning left to face partner.|
|9-16||Repeat 1-8, swapping roles for odds and evens.|
Everyone will face up at the end of beat 10 (original beat 2) and down at the end of beat 14 (original beat 6).
|Figure 5:||Vortex Reel|
|This figure is twice as long as the others.|
|1-8||Middles face person on right and pass left
shoulder to start heys for 3 on the sides.|
Time this to be in home positions on beat 8, ready to continue the hey.
|9-12||3&4 continue the hey to the end of the line
(5&2 positions respectively). Loop as normal but do not return yet.|
5&2 continue the hey to the other end of the line (6&1 positions respectively).
1&6 meet in middle of set, take stomach hold right and turn three quarters, then dance out through the middle of the opposite side and turn left to join the other hey from 4&3 positions respectively.
|13-32||Repeat 9-12 five more times from new positions.|
Those in 5&2 positions must make sure they allow those who have just come out of the stomach turn to pass left shoulders before proceeding.
Finish with a hoy, with everyone facing out on the sides in their home places.
|No lead off; wait until you the signal from the musicians and walk straight out into audience in the direction you're facing.|
