Almost 50 years on and Dick Van Dyke can still perform a fantastic version of “Chitty Chitty Bang Bang”.

The 90-year-old was dining out in Santa Monica, California when the legendary actor performed an impromptu rendition of the song with three other men.

Posting a video of the performance on Facebook, Van Dyke added the caption: “Breakfast at Denny's, with a side of grits makes me want to sing!”

Chitty Chitty Bang Bang - which co-starred Sally Ann Howes, Robert Helpmann, and Benny Hill - was released in 1968 and is a loose adaptation of the book of the same name by James Bond author Ian Fleming.

Last year, Van Dyke starred in the award-winning short film Merry Xmas in which he plays a father getting divorced during the holiday period. The pair’s children - played by Matthew Modine and Glenne Headly - race home to prevent the break-up.

The actor is also rumoured to feature in the upcoming remake of Marry Poppins, starring Emily Blunt as the titular character.
