My Life on a Diet, Renée Taylor’s hilarious one-woman show (cowritten and codirected with Joseph Bologna, her late husband), is a testimony to the power of a story and the story teller. In a beautifully beaded champagne evening dress and matching sneakers, she’s the size of a pixie and just as energetic. When she told her doctor she’s going to do a one-woman show, he wonders how, at 86 years old, she’s going to move around the stage for an hour and a half with arthritis, bursitis, sciatica, the beginning of osteoporosis and a broken foot? She tells him “I can jump! I can kick! I can do the mambo!” Then she admits: “In the pool. On dry land, I can walk and I can sit. I just have trouble sitting after I walk and getting up and walking after I sit.” So, she arrives at a happy medium and stays seated for her performance.
