Abby Hadfield is a stage actress who was one of three women brought in to audition for the vacant position of female performer on the second season of The Muppet Show, after Eren Ozker left the production. Unlike Richenda Carey, who preceded her, Hadfield puppeteered in at least some of her segments, which included the characters Zelda Rose, Green Frackle, Lydia, and a female Whatnot in "The Entertainer," all from episode 203. This would be her only episode, as Louise Gold was brought in for the next episode and remained with the show for the rest of its run.
Hadfield's background lay in Gilbert and Sullivan, serving as a member of the D'Oyly Carte Opera Company from 1963 to 1970, and again in 1971. As understudy to the principal mezzo-soprano and later a regular performer in her own right, she played such roles as Edith (and later Isabel) in The Pirates of Penzance, Lady Angela in Patience, and Tessa (and later Vittoria) in The Gondoliers. Her screen credits include chorus roles in the 1965 TV version of Patience and the 1967 film of The Mikado. In 2000, she was one of many D'Oyly Carte alumni featured in the video Together Again: A Tribute to Kenneth Sandford, John Reed, and Thomas Round. Outside of Gilbert & Sullivan, she made an appearance on the popular soap opera Coronation Street..
