Ethel Merman (Zimmermann) and Russell Nype sang "You're Just In Love" (Irving Berlin) in the original 1950 Tony Award winning production of "Call Me Madam". Wikipedia: "Theatre lore has it that Berlin wrote the song one night after Call Me Madam was not doing well in tryouts. The second act of the show was lacking. "What I'd like to do is a song with the kid (Russell Nype)," Merman said. So, Berlin went to his room and later produced the counterpoint song. When Berlin played the song for Merman, she said, "We'll never get off the stage." Reportedly, Berlin played the song for Russell Nype first, but admonished him not to admit he did so because it would infuriate Merman."

Perry Como and The Fontane Sisters (Bea, Geri and Marge Rosse) charted at number five on Billboard with "(I Wonder Why) You're Just In Love" in 1951. Fontane Drive in Cornwall, New York was named in their honour. In Cannonsburg, Pennsylvania you will find Perry Como Avenue. You will also find a street in Palena, Italy renamed for Mr. C.
