Surviving Beatles Paul McCartney and Ringo Starr reunited at Abbey Road Studios on Thursday night to mark the 50th anniversary of their classic album of the same name.
The last two members of the Fab Four attended a party at the legendary London address alongside Paul's wife Nancy Shevell and Ringo's spouse Barbara Bach.
The pair were pictured arriving separately, missing the opportunity to recreate Abbey Road's iconic album cover image of The Beatles walking on the pedestrian crossing outside Abbey Road Studios together, as many fans had throughout the day.
Although the record - which first went on sale on September 26, 1969 and is reissued today - was the penultimate released by the group, it was the final one they recorded as a band before their official 1970 split.
Paul was also interview by Take That's Gary Barlow for his BBC Radio 2 show, in which he describes how The Beatles, who enjoyed phenomenal success over a seven-year recording career, grew as songwriters.
"I think that was purely that we were young guys who just would've got bored if we'd have got a formula," he said. "So it's like 'Let's do this', we were just trying to amuse ourselves and entertain ourselves and so we were getting better.
"And lyrics, consequently, got better, the arrangements got a little bit more intriguing and we cut them back to make some bluesy thing or whatever.
"It was always just trying to do something that we liked, that entertained ourselves and in doing so we assumed that the fans would pick it up."
