This dance is a fugue; the M copy the W 8 bars later.
Note: This crib follows the current way of dancing. In the original instructions, the promenade [25-32] is cclw. Bill Hamilton said in 'hindsight' this promenade should be clw, but preferred not to change the official instructions. Bill disapproved of another variant, where the circle [121-128] is continued to the R only.
Note that both times the couple moving UP makes the arch.
Note on [27-28]: originally 2 PdB. modified by Drewry to SkCh. O. Otto says best variant is corners in PdB, 1c in SkCh
Alternative for [1-8]: 1c ends on own side. See 101 SCD and Manual
In 17-32, the corners traditionally set one bar to the person you just passed, then one bar to the next person to pass. In a variant for [19-24] 1c turns BH in PdB.
Note: [3-4] is NOT in DTr position.
Note: on  the original says »RH«, but »BH« is widely used.
The first two turns are in Strathspey time, the second two are in Reel time.
A quote: »the key that has always made this dance so wonderful is the flirting that dancing couple can do on bars 9-10 and 13-14 ; <...> if you actually set to your partner, advancing and at the last moment just slipping in BtoB to face and turn the appropriate corner, it's tremendous fun. The moment is all too rare, as apparently few teachers teach it this way, but it's a moment I savour.
Note: older instructions tell 1c to turn once LH on 23-24; the current (revised) instructions leave that unspecified.
Note: The dry white sands on the north-west side of the Isle of Eigg are said to produce a musical sound when walked upon.
