It is five years ago to the day that the Queen and Duke of Edinburgh officially opened Leicester's iconic Curve theatre during a royal visit to the city.
Tonight, to mark the fifth anniversary, the theatre will roll out the red carpet to 800 lesser known but equally valued VIP guests for the opening night of its latest original production, Chicago.
The guest list includes builders, volunteers, actors, dancers, directors and past employees who have contributed to the Curve story.
Chief executive Fiona Allan said: "We're going to have a packed house and every seat has been given away.
"It's something we've never done before but wanted to do it as a gift to the people who have been involved with Curve since its conception, from tradesman who worked on the building to actors and, of course, our loyal customers."
Among the 800 VIPs at the champagne reception will be 200 winners of a Mercury competition.
Readers were asked to say what being there on Chicago's opening night and Curve's fifth birthday would mean to them.
Ruth Beardsley, 37, of Birstall, won a ticket for herself and partner Nigel.
She said: "It will be the first time I've had the chance to catch a show at Curve. I can't wait.
"We're both very excited. I think Leicester is very lucky to have Curve.
"It's a striking building right in the centre of a really happening cultural quarter.
"To have all these wonderful productions on our doorstep is fantastic."
Greeting guests will be Vanita Maisuria, of Belgrave, Leicester, who has worked at Curve in a variety of roles since day one.
"I've been here from the very start and remember it being built," she said.
"I was looking for something challenging and have loved every minute of it."
Vanita has worked in the bar, ticket office, as an usher, receptionist and waitress in the theatre's new Mezzanine restaurant.
"They tell you not to be star-stuck when all these famous actors and other people visit but sometimes you can't help it," she said.
"The most memorable day for me was actually when the Queen opened the theatre.
"I was on the door and had to hold it for her when she walked through."
Ms Allan said: "Vanita is one of our unsung stars, and one of the many dedicated people who have been integral to our success.
"Every single person plays their part and it's a very special environment."
Chicago is one of the latest in a line of original productions staged by Curve, which has made a name for itself as one of the country's top producing theatres.
A mixture of home-grown talent and touring shows have appeared at the theatre in the past five years, including the multi-million pound world premier of Finding Neverland, involving top Hollywood producer Harvey Weinstein, last year.
Curve's artistic director Paul Kerryson said: "Time flies by when you're having fun. It's been hard work but very enjoyable.
"Leicester audiences have grown to love the theatre and we're very proud of our achievements.
"But you can never stand still – you've got to keep things fresh."
