I did notice the wikipedia article said it was Ringo's first session, which June 6 was not. So Sept. 4 makes sense.
How did this turn into a "Film" as some are now posting here? The article only mentioned "Recording".
Funny, looking at this again, Emerick was born 5 December, 1945. That is, he had turned 16 at the end of 1961.
I think there was another article - this time from the other oracle of truth - The Sun, which referred to a film. I put it down to poor / lazy journalism.
The confusion is the OP didn't mention anything about a video: Nevertheless, the original story is in the Sun: A COURT battle is set over a demo recording of The Beatles — thought to be worth around £5million. The video shows the band performing for the first time at Abbey Road Studios. It was discovered in the estate of the group’s ex-sound engineer Geoff Emerick, who died aged 72 in 2018. The tape belonged to EMI — which was acquired by Universal Music Group in 2012. Mr Emerick, who worked for EMI, said he was told to destroy the recording because it was not of good enough quality. But he secretly kept it in its original box in a safe at his Los Angeles home. A legal showdown between his family and Universal over who should have the tape is expected to begin in California on Tuesday. A source said of the video from June 6, 1962: “It’s an amazing find. "It’s been estimated at £5million but could be worth much more.” It was filmed before Ringo Starr joined as drummer. Songs include Love Me Do. Mr Emerick’s family argue they are entitled to keep it because of finder’s law. Universal say the law does not apply because he had been told to destroy the recording. The source added: “Despite wanting it destroyed, Universal all these years later want it back. They know how huge this find is." Major court battle worth £5 million set over a secret demo of The Beatles Clearly something was lost in translation. Actually, several things. Which then got worse when the Daily Mail picked up the story: The Beatles' old Abbey Road jam session worth $5 million is 'at the heart of legal battle' | Daily Mail Online
Is it possible the Sept 4 session was the one they played the slow Please Please Me. The Andy White version would be at the session a week later. Beatles Bible mentions it being recorded on the Sept. 4. session, if not recorded at least rehearsed.
Ernst Jorgensen (who looks after Elvis Presley's archive) has a policy of "no questions asked" when somebody wants to return a record company tape, even if they are trying to sell the tape to him. The difference between Elvis and The Beatles archive releases is frequency, Elvis has had multiple releases every year for the past 20 years with a total of almost 200, so Ernst is desperate for unreleased material they don't have in thier archive. The Beatles can play hard ball and go the court route even if it takes years because a project to release this tape might not happen for 10 years.
Not this tape but The Beatles also had a jam session at Abbey Road in 1964 ? with Carl Perkins. I think Perkins took the only tape with him after the session.
He (apparently) visited the Matchbox session, but there's no evidence he ever played with them. Was There A Carl Perkins Recording Session With The Beatles in 1964?
