Australian singer John Farnham's health worsens, preventing attendance at his tribute concert in Melbourne

Australian music legend John Farnham will not attend a tribute concert in his honor at Melbourne's Rod Laver Arena on Sunday due to his deteriorating health. The 77-year-old singer, who battled oral cancer, now requires continuous oxygen support and 24-hour nursing care. His family announced this on Saturday, saying they kept his condition private while adjusting. The sold-out concert features stars like Jimmy Barnes and Keith Urban and raises funds for Head and Neck Cancer Australia, which supported Farnham during his treatment.
