In his book, "The Willow Tree", Hugh gives Dusty Windowsills and The Battering Ram as sample tunes, and specifies 48 bar double jigs.
Although the article says that the bottom couple should start the Strip the Willow with the left arm, and be on their own side for the arches, these elements are not specified in the book, and I have never seen anyone do them - the default for StW is a right arm start, and the swing will sort out which side you are on.
Hugh got the idea for the second half of the dance from Gort met Stroop, a Dutch dance. The first half goes way back to pre-1650 in The Old Man with a Bed full of bones.
