Henry & Jacqui vs Jacqui & Henry, notes from Scott: 
These dances are identical in the Bs. The petronella-to-swing transition is the highlight of each, but the set-up varies dramatically. The original, easy dance (H&J) is a bit repetitive in the As, and is double-progression. It took years of experimentation (many too-bland versions) to devise the latest model (J&H), which is single progression, and more challenging.
