During Thanksgiving dinner, one of the guests, Lana, said some very complimentary things about me and I responded by saying nice things in return. Of course, I then started singing, "We belong to a mutual admiration society." My nephew Michael said, "That must be from a Broadway musical." Lana said, "Yes, I know it! What is it from?" My niece Tracey said, "The Pirates Of Penzance". I said, "Nah, it's not THAT old!" She answered, "I always say The Pirates Of Penzance for any old musical!" I laughed and said, "You'll be right ONE day!"
I only remembered Teresa Brewer singing it in the 1950s but I don't think she was on Broadway. Lana said she would think of the musical before the end of the day. I said that I would also! I said that I knew it had to be an old musical because my mother used to sing the song when I was a kid. Neither Lana nor I recalled the musical and when I looked it up, I learned it's from the Broadway musical Happy Hunting which starred Ethel Merman. I'm certain I never heard the entire musical, only the song.
