Grimstock
for a line of three couples.
Reconstructed by popular opinion and Dafydd Cyhoeddwr.
Music: Danses Populaires Francaises by the Broadside Band, among others.
Part 1
Verse 1, Part A
1: Forward a double.
2: Back a double. Face your partner.
3-4: Set and turn single, left.
Verse 1, Part B
1-2: Forward a double and back. Face your partner.
3-4: Set and turn single, right.
Chorus 1, Part A & B
1-4: Men and women do a mirror single hey, starting with the first couple going "between" the middle couple, etc.
The trick to these heys is to remember that when you are going from an end toward the middle, you are going between the couple coming toward you, and when you are going from the middle to either end, you are going around the couple coming toward you.
The previous hint is courtesy of Lady Aresua.
Part 2
Verse 2, Part A
1-2: Side left with your partner.
3-4: Set and turn single, left.
Verse 2, Part B
1-2: Side right with your partner.
3-4: Set and turn single, right.
Chorus 2, Part A & B
1-4: Mirror hey with hands.  This is exactly like the previous hey, except partners hold hands throughout, so when you are going into the middle of the set, you are ducking under an arch, etc.
Part 3
Verse 3, Part A
1-2: Arm left with your partner.
3-4: Set and turn single, left.
Verse 3, Part B
1-2: Arm right with your partner.
3-4: Set and turn single, right.
Chorus 3, Part A & B
1-4: Crossover hey.  For couples 2 and 3, this hey is exactly like the first mirror hey (the one without hands).  For couple 1, as you go into the middle, change places, and at the other end as you are coming into the middle again, change places again.
