La Cantatrice chauve
The theater began showing Ionesco's The Bald Soprano ("La Cantatrice chauve)" followed directly by The Lesson on 16 February 1957. This was a revival of "The Bald Soprano" as the play on its own had been poorly received by critics and the public on its own, performed at Théàtre des Noctambules in 1950 before being stopped short after only 25 performances. As of February 2017 the two plays have been performed more than 18,000 times the theater, holding the record for longest running show without interruption at a single theater.
