Soul singer Merry Clayton is facing a long recovery following a car crash in Los Angeles, according to her manager. The star, whose back-up vocal work for Ray Charles and the Rolling Stones was documented in Oscar-winning film Twenty Feet From Stardom, was left severely injured in the smash last week (ends22Jun14). A post on Clayton's official website after the accident revealed she had suffered "major trauma to her lower extremities", and now her representative Alan Abrahams reveals the performer is staying strong despite the difficult situation. He tells the New York Post's Page Six column that Clayton has "a long road to recovery", adding: "It's a very serious situation. She's feisty, and she's with us. She's gonna make it."
