Micky Dolenz, the final surviving member of the Monkees, has requested that the FBI make any information it may have about the group and its members public.
Dolenz, 77, filed a complaint on Tuesday through attorney Mark Zaid asking the Department of Justice to release copies of documents the FBI possesses on the group.
In Dolenz's case, it is claimed that the FBI "maintains responsive records involving the Monkees, including information that continues to be withheld."
Since June 23, according to the lawsuit, Dolenz has not heard anything from the FBI.
The 1960s musical group The Monkees gained popularity on the NBC comedy "The Monkees." Dolenz, Davy Jones, Peter Tork, and Michael Nesmith were the members of the group.
Seven heavily redacted pages from FBI archives about The Monkees can be found online, including reports from an agent who reportedly attended a 1967 concert.
The FBI should "disclose its secret Monkees files and assist the public understand more about a crucial period of American history," said Zaid, Dolenz's attorney.
