London's West End is lagging behind its American equivalent Broadway according to musical veteran Sir Andrew Lloyd Webber.
He says it's due to a shortage of theatre space which means there is nowhere to try out new material and "get it wrong".
The musical veteran said that the capital could learn from show bosses in New York's theatre distinct, who have a chance to develop and perfect new productions away from the limelight "off Broadway", thanks to more available venues.
The thing we have to think about right now in Britain is that America has basically taken the lead again.
Lloyd Webber has now matched a record set by musical theatre team Rodgers and Hammerstein with four productions on Broadway due to the return of his show Sunset Boulevard.
