The cast of Grease remains devoted to their beloved Sandy Olsson. Those who acted alongside Olivia Newton-John are remembering her life and her legacy after she passed away on Aug. 8 at the age of 73 years old, as her husband shared in a statement to her Instagram. While many will always remember Olivia for her singing and acting, those who worked close with her have proven she will be remembered for a number of qualities beyond her sheer talent. For Stockard Channing, who played the fiery and sarcastic Betty Rizzo, Olivia's essence will stay with her. "I don't know if I've known a lovelier human being," Stockard shared in a statement to E! News. "Olivia was the essence of summer—her sunniness, her warmth and her grace are what always come to mind when I think of her. I will miss her enormously." And that warm and bright energy even translated over an email. Barry Pearl, who played Frenchy's boyfriend and member of the T-Birds Doody, shared with E! News that Liv always signed her emails to him with 'Love and Light, Olivia.'"
