A footnote. Lisa Kirk, who did the dubbing for Roz Russell in Gypsy, was actually a first-rate singer/performer/actress--though not a "belter." Her career never got its due. She had the "Lois Lane" role in the first stage production of KISS ME KATE (the role Ann Miller played so marvelously in the movie) and was splendid. And then she starred in the ill-fated musical ALLEGRO, which bombed--as it should not have, and was brilliantly revived a few years ago by ENCORES!--though obviously no longer with Lisa Kirk.
Good for you, though--totally right after Jean Simmons and I'd not thought (or probably ever known!) about that! Still, Susan's contribution was exceptional, since her musical ability dominated the picture and, at lest for me, made me wish she had done more dramatic musicals (even her mediocre number in Valley of the Dolls ought to have been actuallly hers).
You know when I think about it -- I do remember Lisa Kirk -- at least I am old enough to remember her. I think I saw her on some '50s TV shows, perhaps Ed Sullivan?
I'm old enough that I remember Lisa Kirk as Lola Lane in Kiss Me Kate and Allegro. Wonderful performance--but of course, Ann Miller stole the movie version with her dancing.
BUT for dramatic actress doing the whole singing numbers in movie,I've got another
IDA LUPINO in ROAD HOUSE
And come to think of it while Garland was a musical star, her performance in A STAR IS BORN was not a musical performance per say but a dramatic feature--in which she did do all the signing.
