Full info here:Zappa had plans to release this historical encore in its entirety after mixing it in 1971, but shelved it after John and Yoko released their own encore mixes on Side 4 of June 1972’s Sometime in New York City. Zappa eventually released his version of the encore as part of October 1992’s Compact Disc, Playground Psychotics.
After being awarded the rights to his back catalogue in the early 1980s, Zappa mulled other plans for releasing the encore, but upon inspection of the returned Fillmore East masters, it was discovered the Lennon encore tape was missing from its master tape box. In 2021 following a request via Universal, the Lennon Estate kindly provided the Zappa Trust and UMe with a high-resolution transfer of the multi-track safety reel (which FZ had made for them in 1971), thus ensuring that, for the first time in 50 years, the full encore performance could be heard, remixed, in its entirety.
