The final few touches are being put in place as Leicester Square is being transformed ahead of this weekend's West End Live.
There'll be performances from some of the big West End shows, including Mamma Mia, Wicked and Billy Elliot.
There'll also be tasters of what London's museums and galleries have on offer.
And Heart's Toby Anstis and Matt Wilkinson will be on stage hosting the event.
