Actor Jeff Goldblum manned a pop-up food truck to hand out free sausages to excited Sydneysiders on Wednesday, April 26, and even sung to some of them.

The Hollywood A-lister was at Wynyard Station and then Circular Quay in a food truck labelled “Chef Goldblum’s”, according to numerous social media posts. One woman posted that he “serenaded me the Jurassic Park theme song! Can’t wipe the smile off my face”.

It wasn’t exactly clear what the star was promoting, but also Wednesday (Tuesday, US time) news broke that Goldblum would return to appear in next year’s Jurassic Park sequel.

In the video above, Goldblum can be seen signing “Hey Jude” with a fan.
