Lloyd Webber said at the event, "Today's celebration is about recognizing the rich history of this wonderful theatre and the fantastic performers who have graced its stage. It is also about the beginning of the biggest program of refurbishment and change in the Palladium's history and I'm delighted to announce the restoration of the iconic revolving stage and plans for the complete refurbishment of the Front of House areas."

Prior to the first performance of The Wizard of Oz in February 2011, the main entrance facade of the Palladium, according to the Really Useful website, will be "fully repaired and refurbished, a new Box Office area will be created with direct access to the theatre, a new lift will improve accessibility to the stalls level and toilet facilities will be improved. The current Box Office will be converted into three new function spaces, the grandest of these will have the historic roof light reinstated and a new spiral staircase will link it directly with the existing Variety Bar."

Among those who joined Lloyd Webber at the 100th birthday celebration were Russ Abbot, Michael Ball, Brian Conley, Jason Donovan, Ken Dodd OBE, Lesley Garrett, Sheila Hancock OBE, Peter Land, Gillian Lynne, Paul Merton, Des O'Connor, Elaine Paige, Nicholas Parsons OBE, Jonathan Pryce CBE, Philip Schofield, Bruce Welch and Hayley Westenra.
