Uncommon moves add fun and interest to this dance, which is straightforward after a careful walkthrough. I've found that saying exactly which hands to keep and which to drop makes things go well.

To form the cloverleaf in A1, keep hands with partner but drop hands with neighbor. Then reach free hand under joined hands to take hands with next neighbor.

The novel A2 cloverleaf-to-line is easy to do despite the wordy description — 1's keep hands with neighbor but drop hands with partner. 2's make an arch, 1's duck through and, still connected with neighbor, continue out to the side and unwind to make a line of four facing down the hall.

In B1 and B2 the center couple should keep hands with each other but drop hands with the side people. Then make an arch and face right (as a couple) so lady #1 can duck through and all swing.

Hats off to Julian Blechner for inventing this "down the hall, arch, and swing" sequence in his dance Ants Marching, and to Donna Hunt for doubling it up in her dance "Tailor-Made for Bill".

Technically this dance doesn't start in the normal "improper" formation, but don't tell the dancers. Begin the first walk-through with a neighbor swing; then when you're ready to start the dance leave everyone next to the neighbor they've just swung rather than backing up to original places.

And here's a (reverse-progression) variant where different people go through the B-parts arches. In A1 do a right and left through instead of a circle, and in B2 arch left instead of right so gent #2 goes through the arch. Point out the wall to your right and tell the dancers they should always arch toward that wall.
