Absolutely, Wystan. And Pygmalion has only one "l". en.wikipedia.org/wiki/Mrs_Patrick_Campbell "In 1914, she played Eliza Doolittle in the original production of Shaw's Pygmalion; though much too old for the part at 49, she was the obvious choice, being by far the biggest name on the London stage, and Shaw would have seen it no other way since he wrote the play for her in particular." en.wikipedia.org/wiki/Pygmalion_%28play%29 "It [Pygmalion] opened in London April 11, 1914 at Sir Herbert Beerbohm Tree's His Majesty's Theatre and starred Mrs. Campbell as Eliza and Tree as Higgins." Pygmalion is the play on which the musical "My Fair Lady" is based.
