American Pie stars enjoyed a night at The Cavern Club - with one of the main characters even taking to the stage.
Thomas Nicholas - who played Kevin in the coming-of-age series - sang a version of Tom Petty's Free Fallin to a delighted crowd.
He also performed Laid and Stiffler's Mum, two songs well-known to fans of the films.
Nicholas was at The Cavern Club with Chris Owen, who played Chuck 'Shermanator' Sherman and Shannon Elizabeth, who played Nadia.
The group were in the famous Mathew Street venue on Saturday night while in Liverpool for Comic Con, which is taking place at Exhibition Centre Liverpool.
Video and pictures from the night out were shared by promoter Dale Roberts, who posted on Twitter: "So last night I stood with The Sherminator and Nadia and watched Kevin from American Pie sing Stifler's Mom, Laid and Free Fallin’."
