3C Chain Progression was earlier known as Chaperoned Chain Progression
Note: In »corners pass and turn«, 1c normally pass Rsh on ; for this dance the instructions explicitly specify Lsh
Unofficial: On 2nd turn, 4c has an easier start if 1c+3c+4c dance a 3c Poussette
Note: Cosh explicitly tells 1c to pass Lsh in [9-24]; however the Rsh pass is quite common, and nicknamed »Mairi's Divorce«.
Note on [27-28]: originally 2 PdB. modified by Drewry to SkCh. O. Otto says best variant is corners in PdB, 1c in SkCh
