Dargason or Sedany is a dance and tune published in Playford's first edition 1651, and republished many times in the past century, e.g.The Complete Country Dance Tunes from Playford's Dancing Master - by Jeremy Barlow. You might find it with Google.
Yes, I suppose there is a likeness.
The tune is the one that Vaughan Williams mingles with Greensleeves, in the Fantasia on ....
The dance starts in a single line, men at one end facing in, women at other end, also facing the middle.
1 Middle man and woman, 'sides'(i.e. go forward, to the side of partner, till R shoulders are near,drop back), set and turn single (i.e. step to the right and step to the left and turn yourself around).
Walk past that one and repeat with next.
You gradually bring everyone in, when you reach the ends you turn and carry on till back to starting place when you start part2
2 R arm turn (linking arms),set and turn single. Pass and repeat.
This figure will die away as everyone gets home
Figure 3. Single Hey (Scottish or American dancers might call this a reel or chain. I.E. give R hand pass, L to next, pass. All the way till all are home.)
