Henry Winkler turned back time to meet the stars of a musical version of his hit TV show Happy Days.
The US star - known to millions for his role as The Fonz in the series - met the cast as they prepared to open a stage run of their production next week.
Henry has been starring in panto in Richmond, south west London, in recent weeks and is billed as the creative consultant for the new show which will open at the Churchill Theatre in Bromley on Tuesday.
It opens a day before the 40th anniversary of the first ever TV broadcast of the 1950s-set Happy Days which was popular around the world.
Henry - who has recently been working with the BBC on an adaptation of his children's book series about dyslexic Hank Zipzer - teamed up with the stars of the musical in a London diner. He was also receiving the freedom of the City of London.
