For roughly the first half of her time on "The Benny Hill Show", she both danced as a member of the Hill's Angels troupe and acted in comedy sketches. As her tenure with the show lengthened, she moved away from dancing in favor of comic acting only. One of Upton's comic character portrayals was the geriatric superheroine "Wondergran". In a later episode, she played Stan Laurel to Benny's Oliver Hardy. Behind the scenes, she became the Angels' unofficial "shop steward" in the show's later years, interceding on their behalf with Hill or with producer Dennis Kirkland when necessary. She also had a hand in the selection of prospective Angels, recommending girls who she thought might be suitable to Hill for auditions.
