High Quality Content by WIKIPEDIA articles! "You`re Just in Love" is a popular song by Irving Berlin. It was published in 1950 and was first performed by Ethel Merman and Russell Nype in Call Me Madam, a musical comedy that debuted at the Imperial Theatre in New York City on October 12 that year. The show ran for 644 performances. Ethel Merman also later starred in the 1953 film version. 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." According to Berlin`s biographer though, Berlin played the song for Russell Nype first, but admonished him not to admit he did so because it would infuriate Merman.
