The mystery deepens...I am quite sure that PETER BROOK was head of the NATIONAL THEATRE before PETER HALL and yet he isn't even listed...and instead you get:

Laurence Olivier was the first artistic director of the Royal National Theatre, in 1963. Shown in a photograph by Carl Van Vechten, 1939

Baron Olivier OM (1963–1973)
Sir Peter Hall CBE (1973–1988)
Sir Richard Eyre CBE (1988–1997)
Sir Trevor Nunn CBE (1997–2003)
Sir Nicholas Hytner (2003–)

Now my father used to take me to 'THE NATIONAL' so often as a child...that I would head there, every time I was in LONDON to 'check it out' and in particular the film theatre as well as the HAYWARD GALLERY...

TREVOR NUNN...that is who we met in PARIS. So this is a case of 'memory modification':

"In 1968, Nunn was appointed Artistic Director of the Royal Shakespeare Company, a position he held until 1986. He was also Artistic Director of the Royal National Theatre, following in the footsteps of Sir Peter Hall. His first wife, Janet Suzman, appeared in many of his productions. Nunn became a leading figure in theatrical circles, and was responsible for many ground-breaking productions, such as the RSC's version of Dickens's Nicholas Nickleby, co-directed with John Caird, and a musical adaptation of the Shakespeare play The Comedy of Errors. A very successful director of musicals, in the non-subsidised sector, Nunn was responsible for Cats (1981), formerly the longest running musical in Broadway's history, and the first English production of Les Misérables in 1985, also with John Caird."

...and doesn't the guy look like TODDY which is worrying...
