Then I watched the MY FAIR LADY show which I had recorded from Ovation.
It was an hour special made at the time of the mounting of the National Theater production of MY FAIR LADY with Jonathan Pryce. It did show that cast in rehearsal and we got a bit of "The Rain in Spain," "With a Little Bit of Luck," and one other song. Very rough and I have to say I wasn't especially impressed with either of the three stars in these rehearsal clips.
However, they did do a backstory on the original 1910 play of PYGMALION, the 1938 movie, Lerner and Loewe's 1956 musical (which one and all pronounced the greatest musical comedy in the history of the medium and then gave their reasons behind calling it superior in construction to Shaw's play), and the 1964 movie. No other stage versions were mentioned.
There was some movie footage of Shaw himself, and of course, plenty of full frame clips from the MY FAIR LADY film and from "The World of Lerner and Loewe" that showed Julie Andrews and Rex Harrison in simulated rehearsal footage. Also present was Kitty Carlisle who kept commenting on how ghastly Julie had been during early rehearsals of the show and how her husband booked a suite and spent the weekend feeding Julie every line of the play in a last ditch effort to get her ready to perform opposite the feisty Harrison: all very well known stories.
