It was a heartwarming trick of editing which left many fans in tears.
In the music video for the Beatles' final song, Now and Then, Sir Paul McCartney and Sir Ringo Starr were seen appearing to perform with John Lennon and George Harrison one last time.
Acclaimed director Peter Jackson - who was entrusted with the band's precious archives to create Disney+ documentary Get Back - cleverly used footage filmed for their 1967 hit Hello, Goodbye to make the scene work.
The Beatles recorded three bits of footage at London's Saville Theatre to promote the track. One - not that which features in Now and Then - then debuted on the Ed Sullivan show in the US in November 1967.
The Now and Then video also shows scenes from footage that was filmed for John Lennon's 1973 song and album Mind Games - after the Beatles had split up acrimoniously.
Among the other archive clips used was a short segment showing Lennon in an electronics shop in Japan in 1979, the Beatles at Twickenham in 1968 and footage of the band performing in Manchester in 1963.
