Glen Campbell's Children Fight Wife's Control

Two of singer Glen Campbell's children have launched a legal fight to gain control of his medical and financial decisions from his wife, Kim Campbell.

The 78-year-old country music singer is in the late stages of Alzheimer's and is living at a long-term care facililty.

Debby Campbell-Cloyd and Travis Campbell claim Kim Campbell is keeping their father "secluded from the rest of the family" which has been "prohibited from participating in his care and/or treatment", according to a petition filed in a Nashville court in January.

The petition asks a judge to appoint conservators and a guardian to protect Glen Campbell's interest.

Neither Kim Campbell nor her lawyer have commented on the legal action, which was originally reported by The Associated Press.

The Rhinestone Cowboy singer and Kim have been married since 1982 and the couple have three children together.

Campbell has been married four times and is the father of five sons and three daughters.
