The Slip
for a line of as many couples as will.
This is an odd version of a progressive dance, in that it only has one figure.
Reconstructed by Dafydd Cyhoeddwr.
Music: This dance requires 1 repeat of the music for each couple dancing, plus 1 for the intro figure.
The English Dancing Master disc 2 by Orange and Blue, and The Ranchers.  The track repeats 5 times, so it would work for a line of 4 couples.
First time through the music
The "A" music - first repeat
1&2: Everyone honor the presence (a nice, slow, reverance)
The "A" music - second repeat
1&2: Everyone honor your partner.
The "B" music - first repeat
1: Man 1 and 2 take inside hands, their partners the same, and fall back a double
2: These people open and close (a step and close away from each other, a step and close toward each other)
3&4: Change places with your partner.
The "B" music - second repeat
1: Take inside hands as before and fall back a double.
2: Open and close as before.
3&4: Change places with your partner.
The second time through the music
The "A" music - first repeat
1&2: The first man leads his partner about halfway down the inside of the line and honors her (how long of an honor depends on how long it takes to get about halfway down).
The "A" music - second repeat
1&2: The first man continues to the very end of the set and honors his partner (ditto above).  The first couple then falls into place as the lasts couple in the line.
The "B" music - first repeat
1: Man 1 takes hands with the last man, his partner likewise, and they fall back a double, and the top two couples do the same (and for everything following as well).
2: Top two and bottom two sets open and close.
3&4: Top and bottom sets change places with their partners.
The "B" music - second repeat
1-4: The two active sets of people do the same as before.
The rest of the dance
The "A" music
1-4: The top couple go to the bottom of the set in two stages, honoring between and at the end.
The "B" music
1-8: The couples that have moved to the end and the top two couples (including the last couple when there's an odd number at the bottom) do the 'fall back, open and close, switch, all of that again' figure.
Playford instructs "the rest following in order", so continue this until the entire line has gone to the bottom, couple by couple and everyone is back where they started.
