One of the main problems in the factory is that the workers want a 7-1/2 cent raise and are willing to go on strike to get it. Nowadays this doesn't seem like much, but the average mill/garment worker in 1954 (when the play was written) made on average about $1.25 an hour, or about $50 a week. The raise would add $3.00 to each paycheck, so the 7-1/2 cents would be about a 6% increase.

A song written specifically for Doris Day, "The Man Who Invented Love" (music and lyrics by Richard Adler), was ultimately deleted in favor of the standard reprise of "Hey There." Day's recording of "The Man Who Invented Love" can be heard on the soundtrack's CD issue, and the deleted film footage can be seen on Warner Home Video's DVD release.
In her autobiography, Doris Day recounted how, as one of only four cast members who hadn't appeared in the Broadway production, it was challenging to fall into the groove of a company that had been playing the show for more than one thousand performances together. She described the experience as trying to find her place in a well-oiled machine.
