The Maid Peeped Out at the Window, or the Frier in the Well
for a line of as many couples as will.
Reconstructed by Dafydd Cyhoeddwr
The structure of this dance puts limits on just what "as many as will" really is - inverting the line in two doubles means you can't have twenty couples in the line.  
Also, the last chorus requires an even number of couples, so keep that in mind as well when setting up to do the dance
