It's difficult to see that this looked good even on paper. In 1968 Gertrude Lawrence had been dead for seventeen years and most people, myself included, knew her only as an adjunct to Noel Coward and whilst there were arguably those who HAD seen her live on stage I doubt there were sufficient numbers to justify such a lavish production. In my case I did, when barely in my teens, see the first film version of Tennessee Williams' The Glass Menagerie in which she played Amanda, a 'straight' non-singing role though I can't say I honestly recall anything about it. I was, of course, aware of the songs with which she was associated - some of the finest of the twentieth century penned by some of the greatest talents in the field from Cole Porter downwards through Kurt Weill, Gershwin and Coward himself - and equally aware that she couldn't carry a tune in a Louis Vuitton purse (musicians in the 'pit' bands of the shows she starred in used to take bets on which note she would start each song on, never, of course, the correct one) so I relished the irony of having her played by Julie Andrews with perfect pitch. The best you can say about it is that it's a prime example of a curate's egg with some pretty fair set pieces like the balcony scene from Private Lives, Porter's The Physician, etc, but overall it's something of a disappointment.
