The recording was apparently made in 1962 during a Beatles performance in Germany. The eight tracks include Paul McCartney singing the Hank Williams song "Lovesick Blues" and McCartney and John Lennon singing "Ask Me Why."
The Beatles company Apple Corps claims the songs were taped without the band's consent. Fuego Entertainment of Miami says it has the legal right to market the recordings.
A federal judge on Friday approved an agreement not to release the recordings until the case is resolved.
