Version #1
From double pass thru formation: Centers roll away from partners and walk around the outside to pass one dancer and Star thru with the next (the one they were facing in the center). Meanwhile the outsides do a Half Square Thru. Finishes in completed double pass thru formation. (author unknown late 1963)
Version #2
From a squared set: All four ladies cross in front of partners to move one position to their left while all four men move one position to their right. Finishes as a squared set, everyone with opposites for partners and the men in original right hand couple position. (Joe McKeown 1970)
