Sir Paul McCartney's 'Carpool Karaoke' skit was the UK's top-trending YouTube video for 2018.
The Beatles legend revisited his hometown of Liverpool with 'Late Late Show' host James Corden for a well-received edition of the popular segment, which culminated with an intimate concert at the Philarmonic pub.
Now, the video-streaming platform has revealed Paul's homecoming was the number-one trending clip in the UK this year.
While 2018 was big for the iconic musician - who released his 17th solo album 'Egypt Station' in September - it's set to continue in 2019 with a rumoured Glastonbury Festival headline slot.
Organiser Emily Eavis previously said: ''We always want him, of course. He's top of our list - but we'll have to see.''
Emily's coy comments came after the 'Hey Jude' legend admitted he would be delighted to top the bill at the festival.
He said: ''I haven't really spoken to anyone about it. It's a little while since we did it. And we did enjoy doing it. The conversation hasn't gone any further.''
Paul's skit came ahead of the Royal Wedding in May - when Prince Harry and Meghan, Duchess of Sussex tied the knot - while the Yanny v Laurel meme and Courtney Hadwin's 'America's Got Talent' performance also made the top five.
Ariana Grande's own appearance gave 'Carpool Karaoke' another spot in the top ten.
