There are many styles in which this tune, published in the (Henry) Playford Dancing Master 11th Edition 1701, is played and danced
Cecil Sharp, 1922
While it seems all are duple minor, the modern interpretations seem to favour having the first couple improper so that dancers interact more with other dancers of opposite gender.

  A1 1-4 Partners side.                                      
     5-8 Partners back-to-back.                              
  A2 1-8 Repeat A1 with neighbor.                            
  B1 1-4 Neighbors turn two-hands once-and-a-half, skipping, 
         and open to face across the set.                    
     5-8 Partners turn two-hands.                            
  B2 1-8 1st couple figure-eight through 2nd couple above,   
         skipping.                                           
   {inactive couples should change places with partner at top
    and bottom while waiting to re-enter the dance.}

Some groups prefer to use Sharp siding (banana siding) rather than traditional shoulder-to-shoulder siding, as in the animation above.

In A2 some groups prefer LEFT shoulder siding and LEFT shoulder back to back.

And, as Philippe Callens pointed out to me (in Flemish, but using the English word “improper”), Playford does not specify whether this dance is proper or improper. — nashjc 2019/04/17 15:44

CHILDGROVE
This appealing tune has defied efforts to unmask its meaning. Chilgrove is a very small village a few miles north of Chichester, but the connection is doubtful. The basic figures of “Childgrove” reappear with new music as *Scornfull Nancy” and “Hunting the Stagg” in several publications of John Walsh.
