Glen Campbell cancels Australia and New Zealand tour
US country music star Glen Campbell has pulled out of concerts in Australia and New Zealand with Kenny Rogers next month, citing health reasons.
The 76-year-old revealed he had been diagnosed with Alzheimer's disease in June 2011.
A spokeswoman for the Rhinestone Cowboy singer said he was not up to "the very long flight that it would require".
It would have been Campbell's last international stop on his Goodbye Tour as he retires from the music industry.
Rogers will continue on the month-long tour, which begins on 10 August in Christchurch, New Zealand, with Australian country artists filling in as special guests.
In addition to seven concerts with Rogers, Campbell had also been scheduled to perform a solo show in Brisbane, Australia.
The singer, known for such hits as Gentle On My Mind and Wichita Lineman, received a Lifetime Achievement Grammy earlier this year.
His spokesman said Campbell was "very disappointed that he is unable to perform for his New Zealand and Australian fans one last time".
