Booth nearly burned to death in November 1979 when, during a drunken attempt to get into his locked flat, he fell into a drum of paraffin. He spent six months in hospital and needed 26 skin graft operations. Shortly after his discharge from hospital, he went to visit an 'old flame', Coronation Street Actress Pat Phoenix. She took him in and nursed him back to full health, and they lived together for six years. Phoenix's own health subsequently declined, and the pair married a few days before her death from lung cancer in 1986. With his third wife, Nancy Jaeger, he had a daughter, Joanna.
