Details are sketchy and unconfirmed — but two major Beatles box sets might be coming our way over the next few months.

Beatlefan magazine has heard from two sources that “a multi-disc Revolver box set is planned for October 26th or October 28th.” Producer Giles Martin revealed last year that a Revolver set was in the works — but no official announcement has been made.

Also said to be released around John Lennon‘s 82nd birthday on October 9th is the already-announced Some Time In New York City box set — which was also previously said to be coming this year but with zero additional details. Beatlefan’s source stated the set will be “including some sort of Blu-ray disc.” Again, no official word has been offered from either Lennon’s label or estate.

Elephants Memory bassist Gary Von Scyoc (pronounced: Von SY-ock) recorded several albums with John Lennon and Yoko Ono — and is featured on 1972’s Some Time In New York City. He recalled Lennon moving swiftly once he was geared up to record: “He respected us individually as players, and he knew no matter what, if he brought us a song, we were gonna come up with something. As far as John coming with those tunes, he used to come the night of, with a new song, every night — for two weeks straight. That’s how we cut the album. Live in the studio is a whole new thing, because we started laying down the tracks, maybe a half-an-hour after we heard it for the first time.”
