(CBS/AP NASHVILLE, Tenn. - Country music legend Glen Campbell, who is battling Alzheimer's disease, has canceled his tour of Australia and New Zealand with Kenny Rogers next month.

Citing health reasons, a spokeswoman said the 76-year-old performer is not up for "the very long flight that it would require."

Rogers is continuing the month-long tour, kicking off Aug. 10 in Christchurch, New Zealand. Australian country artists will fill in as special guests. Campbell was also scheduled to do a solo show in Brisbane, Australia.

A Country Music Hall of Famer, Campbell received the Recording Academy's Lifetime Achievement Award this year. He is known for dozens of hits such as "Gentle on My Mind," "Wichita Lineman," and "Rhinestone Cowboy."

Campbell wrapped up the domestic leg of his tour June 24 with a performance at the Hollywood Bowl in Los Angeles.
