It is a festival known for its spontaneous outbreaks of singing and dancing as thousands of visitors mingle with the participants.
And when Prince Charles was asked to join in with a group of bhangra performers, the heir to the throne did not disappoint.
Charles's moves may have been restricted by his suit and tie, but he gamely joined hands with members of the Punjabi dance troupe to perform a royal jig.
The 66-year-old was pictured with the Sheerer Punjab Bhangra Dance group at the Llangollen International Musical Eisteddfod, of which he is patron.
