The older children of country icon Glen Campbell are trying to wrest control of his care away from his wife.

The Associated Press reports that Campbell's two oldest children, Debby Campbell-Cloyd and Travis Campbell, filed a petition in January, asking a judge in Nashville to appoint conservators and a guardian to protect their father's interests. They claim his wife of 32 years, Kim, is keeping Campbell "secluded from the rest of the family," and that they have been "prohibited from participating in his care and/or treatment."

The petition is sealed, but a copy sent to the Associated Press accuses Kim Campbell of not providing her husband with appropriate toiletries and clothing, not visiting him regularly and possibly mishandling his finances. The filing further claims that several of his eight children are not on the list of people allowed to visit him at the care facility where he now resides, and that Kim has allowed him to be filmed and interviewed at the facility even though his Alzheimer's has progressed to the point where that is not appropriate.

Kim Campbell referred the AP's questions to her attorney, Bill Harbison, who declined comment, citing the fact that the petition is under seal from a judge.

Campbell ended his career with one final song, "I'm Not Gonna Miss You," which appeared in the documentary film Glen Campbell: I'll Be Me. The song took home Best Country Song honors at the 2015 Grammy Awards, and was nominated for an Oscar for Best Original Song.
