Amelia and Abigail are the two bold geese sisters who rescue O'Malley from the river and lead the way out of the country back to Paris. These comedic characters sing a duet (but no solos), so cast solid singers and actors. It's also important for Amelia and Abby to be able to move convincingly as geese. If you have a small cast, consider double casting them as Alley Cats in the opening number and for "Ev'rybody Wants to Be a Cat".
