After close to 8 years at the Victoria Palace Theatre, it is nearly time to welcome the 4 millionth visitor to Billy Elliot.
A special surprise is in store for that lucky person, and folks are urged to keep an eye on their Facebook page in the next couple of weeks for updates.
Meanwhile, producers appreciate every one of the people who have previously seen the musical, and invite them to see where they fit into Billy Elliot history.
So the Billy Elliot Facebook page includes a 4 million visitors app where it's possible to ''see what was happening in the world of Billy the first time you came to see the show.''
Fans can also tag the friends who came along, so they can see their part in history too.
