I saw all of the original Broadway Dolly's except for Phyllis Diller. I saw Merman three times. She was my least favorite Dolly, and on the third time (three weeks before the show closed) I actually hoped that she would miss the performance and I would get a chance to see Bibi Osterwald, her stand-by.
It was interesting to see Merman because she was a Broadway legend, and it was the only show in which I ever saw her. When I first saw her in the show, as she began to sing "I put my hand in here" in those characteristic loud tones, someone in the row behind me said, "That's Ethel!"
One time I greeted Ms. Merman as she entered the stage door (in a cordial way and from a respectable distance) and got a chilly reception in return.
In the "Collector's Edition" of Hello, Dolly! released a few years back, you can hear the two songs added to the show for Merman - World Take Me Back (inserted in a scene at the Yonker's Feed Store, right before Put On Your Sunday Clothes) and Love Look In My Window (sung on a New York Street prior to Before the Parade Passes By). Although the "Collector's" recording includes the Channing original cast, there are additional renditions of numbers from the Pearl Bailey and Mary Martin (London) recordings of the show, as well as those two Merman added songs.
In another note: The traditional green skirt and lilac blouse worn by Channing and most of the other Broadway Dolly's during the end of Act I became a pink outfit during Merman's run with the show.
Although Carol Channing went on to revive the show at a much older age, she was the youngest woman to portray Dolly during the original run of the show and Merman was the oldest.
