Leeds is home to the refurbished Grand Theatre where the only national opera company outside London, Opera North, is based. The City Varieties Music Hall is one of the UK's few remaining music halls, and famously hosted performances by Charlie Chaplin and Harry Houdini. It was also the venue of the BBC television programme "The Good Old Days". The newest theatre, containing two auditoriums, is the Leeds Playhouse, which had formerly been known as the West Yorkshire Playhouse. Just south of Leeds Bridge once stood The Theatre which hosted Sarah Siddons and Ching Lau Lauro in 1786 and 1834, respectively.
