It was the day Ringo Starr got away with the help of a girlfriend, Heather, Paul McCartney’s stepdaughter.
The six-year-old happily picked up the drumsticks as the Beatles practiced in the studio in January 1969.
Momentary footage appears in a four-minute trailer for the six-hour documentary Get Back, compiled from footage locked in a safe for more than half a century.

Heather, daughter of McCartney’s bride-to-be, Linda, is also seen performing with John Lennon.
The three-part documentary uses material shot for the 1970 film Let It Be and includes the Beatles’ last live performance together – the rooftop concert at their Apple headquarters in Savile Row, London.
It will air on Disney + for three days next month.
The latest trailer also offers a rare image of the band’s first manager, Allan Williams, in a recording studio with Sir Paul and Lennon.
Mr. Williams – who is affectionately known as “the man who gave the Beatles” – quit working with the group in 1961 when they were on the verge of becoming a star.
He is widely recognized as the man who gave the Liverpool band their big shot when he led them to Hamburg in 1960 – their first foray into the world stage.
But they argued over a commission and he stopped working with them before warning eventual Beatles manager Brian Epstein not to hit them “with a pole.”

Mr. Williams died in 2016 at the age of 86.
The new documentary follows Lennon, Sir Paul, George Harrison and Sir Ringo Starr and their creative process as they write and rehearse 14 new songs in preparation for their first show in over two years.
The tracks were originally intended to be released on an accompanying live album.
The documentary’s producers include Sir Paul, Sir Ringo, Lennon’s former wife Yoko Ono and Harrison’s former wife Olivia.
