Hollywood star John Travolta wowed guests at a charity ball when he performed an impromptu Grease-style dance with his wife, Kelly Preston.
John Travolta is an avid believer in the Church of Scientology
The usually private actor, famed for his dancing roles in movies such as Saturday Night Fever, leapt from his seat at the event in West Sussex.
Thousands of people packed the Church of Scientology in East Grinstead hoping to see the Pulp Fiction star.
Travolta, 51, took to the stage to dance to soul classic Stand By Me.
Other performers flown in for the fundraising event at the church's UK headquarters included Broadway singer James Barber, musician Mark Isham and female vocalist Elena Roggero.
Organisers of the event, the International Association of Scientologists, said Travolta - who pilots his own private jets - had flown in especially for the gala ball, and was expected to leave on Monday.
During the concert cheques were presented to a number of UK charities including those affected by the 7 July bombings.
Travolta and his wife also presented a cheque for £40,000 to the Sheriff of New Orleans, Harry Lee.
The Face Off star and Ms Preston helped police in the city in the aftermath of Hurricane Katrina.
Sheriff Lee told the concert audience: "After Katrina I was up to my elbows in alligators and looked up and there was John and Kelly.
"Not eight weeks later, here I am 10,000 miles away in a room full of the most committed people I have ever met."
Travolta is a firm believer in the Church of Scientology along with fellow Hollywood legend Tom Cruise.
