Let me fill you in on a few things, TheaterBaby:
The Goddess Carol (TGC) made her Broadway debut in a revue called LEND AN EAR in the early 50's. This was followed by GENTLEMEN PREFER BLONDES, in which she introduced the world to the song about Rob's family, "Diamonds Are a Girl's Best Friend". From there she replaced Rosalind Russell in WONDERFUL TOWN, and later toured in many productions of plays by George Bernard Shaw; most notably THE MILLIONAIRESS. She returned to Broadway in shows like THE VAMP and SHOW GIRL, but HELLO,DOLLY! truly became her signature role.
She reprised GENTLEMEN PREFER BLONDES in the late 60's, only it was called LORELEI. As the original Broadway run of TWHM was winding down in 1970, TGC was across the street at the Broadhurst, where she starred with Sid Caesar in Abe Burrows' comedy called FOUR ON A GARDEN. She also toured in JERRY's GIRLS and SUGAR BABIES (with Robert Morse). After the death of Gracie Allen, TGC teamed up with George Burns, performing many of the routines made famous by Gracie.
Yes, TGC will always be associated with TWHM because she has toured extensively in it. Right now they are trying to mount a revival of the show, but most actresses are turning the role down because they are afraid of essaying a role so closely associated with such a magnificent talent.
