The order of the Dollys on Broadway were
Carol Channing (Jan 16, 1964-Aug 7. 1965)
Ginger Rogers (Aug 9, 1965-Feb 25, 1967)
Martha Raye (Feb 27, 1967 - June 10, 1967)
Betty Grable ( Jun 12, 1967-Nov 5, 1967)
Bibi Osterwald (Nov 6, 1967-Nov 11, 1967)
Pearl Bailey (Nov 12, 1967 - December 24, 1967?)
Phyllis Diller Dec 26, 1969 - Mar 26, 1970)
Ethel Merman (Mar 28, 1970-Dec 27, 1970)
Then there were the Standbys:
Jo Anne Worley,
Bibi Osterwald (who went on a lot for Ginger Rogers and played it for a week before Bailey),
Thelma Carpenter (She went on for Bailey more than 100 times and eventually did Wednesday matinees and played the role when Miss Bailey left)
Marie Bryant (who I have never heard of).
From what I understand Carol Channing and Ethel Merman never missed a performance. Not sure about Miss Raye, Grable or Diller. Mr. Herman does not have nice things to say about Miss Raye.
