THE WITCHES BREW
Rod Linnell, 1965 - Via David Smukler
Triple minor improper double progression

A1- Top 4 RH star; those two ladies swap and LH star back 3/4 (1st
    progression)
A2- Circle 6 hands to the left, all the way round
B1- Actives balance and swing the next below (2nd progression)
B2- Same couples R&L four

So some couples start on the star and others on the balance and swing.
2s stay 2s and 3s stay 3s.
