London Calling! was a
musical revue, produced by
André Charlot with music and lyrics by Noël Coward, which opened at London's
Duke of York's Theatre on 4 September 1923. It is famous for being Noël Coward's first publicly produced musical work and for the use of a 3-D
stereoscopic shadowgraph as part of its opening act. The revue's song "Parisian Pierrot", sung by
Gertrude Lawrence, was Coward's first big hit and became one of his signature tunes.
