Pat Carroll, The Little Mermaid, 1989.        "An answer to a prayer," said Carroll on winning her lifetime’s ambition - voicing a Disney character.   Ursula had been designed for Bea Arthur - far too busy with The Golden Girls, 1985-1992. Next? Wilson, Divine ( at Disney ?!), Charlotte Rae, Roseanne and the Absolutely Fabulous Jennifer Saunders. Plus a slew of veteran ladies: Coral Browne, Nancy Marchand, Sylvia Sidney - and Elaine Stritch, who won the gig, then lost it after disputes with lyricist Howard Ashman.
