I found this on the Rhino Records website:

UNITED STATES DEPARTMENT OF JUSTICE
FEDERAL BUREAU OF INVESTIGATIONS
PHONOGRAPH RECORD ENTITLED
"REHERSALS FOR RETIREMENT"
BY PHIL OCHS
THREAT AGAINST THE PRESIDENT

{name blackened out} made available a phonograph record entitled "Rehersals for Retirement" by PHIL OCHS, distributed by A & M Records, 1416 North La Brea, Hollywood, California. The record was purchased by her 14-year-old son, STANLEY THOMAS, at Osco Drugs, Southwest Shopping Center, Little Rock, Arkansas.

This record was monitored on October 20, 1969, and on side one the first song, entitled "Pretty Smart On My Part," states in song what appears to be: "I can see them coming. They are training in the mountains. They talk Chinese and spread disease. They will hurt me - bring me down. Some time later when I feel a little better we will assassinate the President and take over the government. We will fry them."

This document contains neither recommendations nor conclusions of the FBI
